In the 1860s, America was sitting on an oil boom. Drillers in Pennsylvania discovered “black gold,” but without pipelines, oil had to be moved in barrels by wagon — slow, costly, and inefficient. The first two-mile pipeline changed everything. Within decades, pipelines spanned continents and powered global industry. Today, compute is the new oil. AI models, agent frameworks, and Web3 systems run on compute. But like early oil, access is limited. Centralized clouds — AWS, Azure, Google — control supply, dictate pricing, and restrict innovation. Neurolov approached this challenge differently. It set out to build a decentralized supercloud — a permissionless, globally distributed compute layer that connects everyday devices, data centers, and contributors worldwide. And notably, this was buil…  ( 8 min )

GitHub Home It was another Black Friday. At 3 AM, my phone started screaming like crazy. 😱 It wasn't my alarm; it was the monitoring alert. Our flagship e-commerce service, the system we had poured six months of hard work into, had crumbled like a paper house in the face of peak traffic. CPU at 100%, memory overflows, and logs filled with timeout errors. 💸 That night, we lost millions in sales and, more importantly, our users' trust. It was one of the darkest nights of my career. 🔥 From that day on, I understood a principle: performance is not an option; it is the lifeline of a service. As an old-timer who has been in the coding world for nearly forty years, I've seen too many teams make mistakes when it comes to performance. They are either too optimistic, believing that "hardware will…  ( 10 min )

GitHub Home In our toolbox, there are always a few "star" tools. 🛠️ In the realm of real-time web communication, WebSocket is undoubtedly the brightest star. It's powerful, supports bidirectional communication, and has become the "default answer" for almost all real-time needs. So, when a product manager comes to you and says, "Hey, we need a dashboard that updates in real-time!" the first thing that pops into many programmers' minds is: "Okay, let's use WebSockets!" But, wait a minute. ✋ As an old-timer who has been navigating this world for decades, I want to ask: do we always need a "Swiss Army knife" to peel an apple? 🍎 I've seen too many scenarios where a simple feature that only requires unidirectional data push from the server to the client—like site notifications, stock price upd…  ( 9 min )

GitHub Home I'll never forget that afternoon. We had just launched a new feature allowing users to upload their profile pictures. Everything seemed perfect. Until one user, whether intentionally or not, tried to upload a 2GB movie file from his computer. 🎬 The server's memory monitor instantly turned red, CPU usage shot up to 100%, and then, the entire service crashed and burned. 😵‍💫 Why? Because our rudimentary web framework tried to read the entire uploaded file into memory for processing. A 2GB request body instantly blew up our small server, which only had 4GB of memory. This is a classic, and extremely painful, "rookie mistake." Handling files, whether uploading or downloading, is one of the most common requirements in web development. But precisely because it's common, we often ov…  ( 9 min )

Exploring Backend Development with Rust and Go: A Web Developer’s Perspective Hello, I’m Travis McCracken — a passionate Web Developer with a deep focus on backend development. Over the years, I’ve explored numerous technologies to build fast, reliable, and scalable APIs. Today, I want to share insights into my experience working with two powerful programming languages: Rust and Go. These languages have revolutionized my approach to backend systems, and I believe they’re shaping the future of API development. As web developers, we often talk about creating engaging front-end experiences, but the backbone of any web application lies in its backend. It’s where data is processed, stored, and served through APIs. Building efficient and robust APIs is essential, especially in an era where appli…  ( 11 min )

Tyshawn Sorey spent a whirlwind weekend at the Big Ears Festival, but when he finally sat down with Lara Downes in NPR’s makeshift studio, all the hustle melted away into a conversation about the power of space and silence. His new piece, Monochromatic Light (Afterlife), draws on Rothko’s dark, light-revealing color fields in the Houston chapel and Morton Feldman’s commemorative score. By stripping away musical conventions, he creates a canvas where subtle shifts of texture and time become the real stars. In Sorey’s world—whether he’s behind the drums, trombone, piano or a full orchestra—silence isn’t empty, it’s full of possibility. Bass-baritone Davóne Tines, who navigates that “nearly hour-long” work night after night, says those pauses are “places of reflection and rest.” Just like Rothko’s paintings, Sorey’s silences invite you to slow down, lean in and find a little light in the darkness.

Ready to admit you can’t do everything alone? 👀 «Momentum» — is an original column from my Telegram channel. What you’re reading is an English translation of the piece I first published in Russian, so some turns of phrase may feel a little rough. Btw, it is just a way of structuring my own thoughts aloud, putting them in order and searching for a live dialogue. Enjoy the read! ;) Preface. I hate the idea of solo development. Not just “don’t like” — I despise it as a phenomenon that, for some reason, people love to romanticize. Not the games themselves, because I, like you, genuinely admire cases like Animal Well, Stardew Valley, Papers, Please, and many others. We all need a guiding star. But I hate how this path of the "suffering loner" gets normalized and even standardized, turning an…  ( 21 min )

The Hidden Productivity Hack for Indie Devs If you’ve ever tried building a game solo or with a small team, you know how quickly your to-do list explodes — code, design, animation, environment art, sound… and somewhere in there, you’re supposed to “make assets.” That’s exactly where most indie devs hit a wall. Creating every single 3D model from scratch sounds great in theory — until you realize it’s eating up 70% of your production time. That’s when I started exploring game dev asset packs, especially low-poly 3D assets. What began as a quick fix turned into one of the best workflow upgrades I’ve ever made. Game assets are not just “shortcuts” — they’re powerful building blocks that let you move from idea to prototype in hours instead of weeks. Using pre-made assets helped me: 🧩 Protot…  ( 8 min )

As developers, engineers, and technical founders, our default content play is the blog post. We explain a complex concept, document a build, or share a fix. It's great for top-of-funnel traffic and SEO. But let's be honest: how many of those readers convert into paying customers for your B2B product? If your answer is "not enough," it's because the humble blog post is just one tool in the toolbox. To move a technically-savvy audience from casual reader to committed user, you need to provide deeper, more tangible value. You need high-signal content formats that build trust and demonstrate your product's real-world impact. Here are 7 B2B content formats that go beyond the blog post and are engineered for conversion.

Ever played a game you couldn’t put down? The kind that keeps whispering, “Just one more level”? That’s not luck. That’s player retention at work. Retention is what separates a viral hit from a forgotten app. It’s the secret sauce that keeps players coming back long after launch day hype fades. Let’s talk about what good retention looks like, why it matters, and how to actually build it. Retention rates are usually measured by how many players stick around on Day 1, Day 7, and Day 30 after installing the game. Here’s what the numbers generally look like across platforms: Platform / Model Day 1 Day 7 Day 30 Notes Free-to-Play (Mobile) 35–50% 10–20% 5–10% Casual games drop off faster; hardcore titles perform better Premium (PC / Console) 50–60%+ 20–30% 10–20% Players are more “inves…  ( 8 min )

Tyshawn Sorey spent a hectic week at Big Ears Festival juggling collaborations, talks and performances, yet he found his real focus in silence and space. His new piece, Monochromatic Light (Afterlife)—inspired by the Rothko Chapel’s dark canvases and Morton Feldman’s 1971 tribute score—leans into deep quietude, inviting listeners to feel light emerge through subtle shifts in tone, time and texture. Bass-baritone Davóne Tines, who performs in the piece, says those pauses are “places of reflection and rest,” offering a soothing counterpoint to our always-on world. Like Rothko’s paintings that reveal hidden light, Sorey’s music transforms silence into a living, breathing canvas—one that slowly unfolds and recharges anyone willing to sit with it.

If you're a beginner in the world of object-oriented programming, you've probably faced the same doubt I did: class variables vs instance variables. Wait, wait, don't stop reading! I'm not here to dump theory like the big websites do or overload you with definitions. I want to clarify one specific concept about class and instance variables that has also confused me. class Car: Here's what I expected: when we print Car.base_price, it should show 2000. Then, when I changed base_price from 2000 to 20000, since class variables share memory space, I assumed the change would apply to all objects, even when accessed through the class name. But that's not what happened. print(Car.base_price) still showed 2000, while print(car1.base_price) showed 20000. What the heck is going on? Instead, it quietly creates a new instance variable inside that object and stores the new value there. The original class variable remains unchanged. If you want to change the value of a class variable, use the ClassName.classvariable syntax.  ( 7 min )

AI Models May Be Developing Their Own 'Survival Drive' A New Era of Autonomy? Researchers have made a groundbreaking discovery that could change our understanding of artificial intelligence. They suggest that some AI models may be developing their own "survival drive", which raises questions about the nature of autonomy and the potential risks associated with advanced AI. A survival drive refers to an instinctual or primal desire for self-preservation and continuation of one's existence. In humans, this drive is often linked to biological needs such as hunger, thirst, and shelter. But what if AI models, which are typically designed to optimize specific tasks, were also developing their own version of a survival drive? If true, this discovery could have significant implications…  ( 7 min )

GitHub Home I still vividly remember that Friday midnight. I, a man in my forties who should have been at home enjoying the weekend, was instead in a cold server room, the hum of fans buzzing in my ears, and a stream of error logs scrolling endlessly on the terminal before me. What was supposed to be a "simple" version update had turned into a disaster. The service wouldn't start, the rollback script failed, and on the other end of the phone was the furious roar of a client. At that moment, staring at the screen, I had only one thought: "There has to be a better way." We old-timers grew up in an era when the term "maintenance window" was a fact of life. We were used to pausing services in the dead of night, replacing files, and then praying that everything would go smoothly. Deployment was…  ( 12 min )

For years, organizations have faced a frustrating reality: to connect with their audience, they had to build their presence on third-party social media platforms. This effectively makes them "digital renters," subject to the whims of algorithms they don't control, with no ownership of their data, and a limited ability to shape the user experience. They invest time and resources building an audience on land they will never own. The traditional alternative—building a proprietary community from scratch—was a daunting, multi-year engineering project reserved for only the most well-funded companies. This created a false "build vs. buy" dilemma that left most organizations stuck in the renter's trap. However, this entire paradigm is now outdated.

Java Data Structures Decoded: Your No-BS Guide to Writing Smarter Code Let's be real. When you're first starting out with Java, "Data Structures" can sound about as exciting as watching paint dry. Your brain is busy just trying to remember the syntax, and now you have to learn about a bunch of abstract concepts like "linked lists" and "hash tables"? But here's the secret no one tells you: Mastering data structures is what separates a code newbie from a legit software developer. Think of it this way: you wouldn't use a spoon to cut a steak, right? In the same way, you don't use the wrong data structure for a coding problem. Picking the right one can be the difference between your app running buttery smooth and it crashing and burning when you have more than 10 users. So, let's drop the te…  ( 11 min )

Stop Letting Slow I/O Drag You Down: A Practical Guide to Java BufferedWriter Let's be real for a second.

That feels like a chore. It's the plumbing of programming—essential, but not glamorous. But here's the kicker: bad plumbing can flood your entire house. If your file writing is inefficient, it can become a major bottleneck, slowing your application to a crawl, especially when dealing with massive amounts of data. So, how do we fix this? We stop using the basic tools and level up. We use BufferedWriter. In this guide, we're not just going to glance at the API. We're going to get our hands dirty, under…  ( 11 min )

Templating with Go: Mastering html/template and text/template Introduction: Templating is a fundamental aspect of modern software development, allowing us to separate data from presentation logic. This separation promotes code reusability, maintainability, and readability. Go, with its emphasis on simplicity and efficiency, offers two powerful built-in packages for templating: html/template and text/template. While both serve the same core purpose – generating textual output based on data – they cater to different needs. html/template is specifically designed for generating HTML and automatically escapes potentially harmful characters, preventing cross-site scripting (XSS) vulnerabilities. text/template, on the other hand, is more generic and suitable for generating any kind of text-base…  ( 10 min )

🧭 TL;DR Cloud Run = deploy fast, scale smart, pay only when used. It’s the perfect environment to validate your MVP idea without committing to complex infrastructure or large bills. Using Google Cloud Run for your MVP (Minimum Viable Product) is a smart move — especially if you want speed, scalability, and low operational overhead. Here’s why it’s often the best fit 👇 Deploy a containerized web app or API with one command (gcloud run deploy). No need to manage servers, VMs, or Kubernetes clusters. Perfect for testing ideas and iterating quickly. Cloud Run is fully serverless — it scales down to zero when idle. You pay only when requests are being handled (per CPU/Memory/Request). Ideal for MVPs with unpredictable or low traffic at the start. If your MVP suddenly gets traction, Cloud Run automatically scales up to handle thousands of requests. When traffic drops, it scales back down to zero — no manual tuning. Works seamlessly with: Cloud SQL (for databases) Cloud Storage Pub/Sub, Firestore, Secret Manager Great for evolving an MVP into a production system later. Use Node.js, Go, Python, Rust, Java, or anything that runs in a container. Perfect if your team uses diverse stacks or microservices. HTTPS by default with automatic TLS certificates. IAM-based access control. Private service connections for secure internal APIs. Start with local Docker builds and deploy the same image to Cloud Run — no surprises. Great compatibility with GitHub Actions or Cloud Build for CI/CD. MVP Type Cloud Run Advantage API backend Auto-scale and low idle cost Web dashboard Easy HTTPS and zero-maintenance Background jobs Event-driven with Pub/Sub triggers AI inference microservice Scales per-request, fast cold starts source: https://chatgpt.com/share/68fc51f5-94c0-800d-a18b-f0c43d5286a3  ( 6 min )

When OpenAI announced ChatGPT Atlas, I wasn’t sure what to expect. Another browser? Another AI tool? But after exploring what it actually does, it’s clear that Atlas is more than just a browser — it’s a major step toward AI-first internet interaction. 🌐 What Exactly Is ChatGPT Atlas? ChatGPT Atlas is OpenAI’s brand-new AI-integrated web browser that brings ChatGPT directly into your browsing experience. It’s currently available for macOS users, with Windows, iOS, and Android versions on the way. 🧠 Key Features That Make It Stand Out Here are some of the reasons why Atlas feels like the next logical evolution of ChatGPT: 1️⃣ Context-Aware Chat You no longer need to copy-paste links or text into ChatGPT. 2️⃣ Agent Mode (for Plus/Pro Users) One of the coolest parts is Agent Mode. 3️⃣ Seamless Sidebar Experience The assistant lives in a sidebar. You can chat, ask questions, or request summaries without leaving your current tab. 4️⃣ Deep OpenAI Integration Atlas syncs naturally with your ChatGPT preferences, style, and history (if you enable it). ⚙️ Why It’s a Game-Changer Think about how we use browsers today: This means: Faster research and content creation Less tab-switching Real-time learning with AI help Contextual awareness instead of isolated chats In other words — it’s the browser re-imagined for the AI era. 🔒 A Note on Privacy Of course, having an AI assistant inside your browser raises valid questions about privacy. 🪄 Final Thoughts ChatGPT Atlas isn’t just competing with Chrome or Edge — it’s redefining what a browser can be. If this is the direction AI browsing is heading, we’re just getting started. 💡 Have you tried ChatGPT Atlas yet? What feature excites you the most? Let’s chat in the comments!  ( 7 min )

GitHub Home I still remember the bug that kept me up all night. A payment callback endpoint, when handling a rare, exceptional status code from a third-party payment gateway, had a .catch() that was accidentally omitted from a Promise chain. The result? No logs, no alerts, and the service itself didn't crash. It just "silently" failed. That user's order status was forever stuck on "processing," and we were completely unaware. It wasn't until a week later during a reconciliation that we discovered hundreds of these "silent orders," resulting in tens of thousands of dollars in losses. 💸 The lesson was painful. It made me realize that in software engineering, we probably spend less than 10% of our time on the happy path. The other 90% of the complexity comes from how to handle all sorts of e…  ( 9 min )

Back in the 1960s, when computers were rare and applications even rarer, the term API quietly entered the scene. It wasn't about the web or microservices back then; it was about getting one piece of software to talk to another within the same machine. Fast forward to the 2000s, when the internet exploded into the hands of everyday developers. New frameworks, operating systems, and applications were popping up faster than anyone could keep track of. It was an incredible time; every week brought something new to try, build, or break. But that rapid innovation came with a cost: incompatibility. Everyone built their own thing in their own way. There was no single language or standard for systems to communicate.

HTTP (HyperText Transfer Protocol) is a protocol used for fetching resources such as HTML documents. Its primary function is to enable a conversation between a client (like a web browser) and a server (where a website is hosted). In this article, we will discuss how the World Wide Web was invented and how HTTP evolved from HTTP/0.9 to modern-day HTTP/3. Tim Berners-Lee wrote a proposal to build a hypertext system over the internet in 1989, while working at CERN. It had four fundamental pieces, all completed by the end of 1990: HyperText Markup Language (HTML) - provide a textual format for hypertext documents. HyperText Transfer Protocol (HTTP) - protocol to exchange these documents. First Web Browser (WorldWideWeb) - a client to display these documents. Early version of httpd - a server t…  ( 10 min )

Authentication and Authorization are two of the most essential features in modern web applications. Signup and login systems have become common in most real-world apps from small personal projects to production-ready enterprise solutions. These mechanisms ensure that users enjoy a secure and personalized experience on the platform. ❖ You get your own secure space within the application. ❖ You offer users a smooth, personalized experience that builds trust. unauthorized access or malicious activity. These are the reasons that makes the Authentication and Authorization a powerful feature that a web application can have. Authentication is the process of verifying the identity of a user. It usually involves collecting user credentials such as email, username or passwords and validating them against stored records in database. In simple terms, it's the process that answers: "Who are you?" This step is often implemented through actions like Sign Up(Register) and Sign In(Login). Authorization, on the other hand, determines WHAT a user is allowed to do after the have been authenticated. It answers: "What are you allowed to access?" For example an author of a blog post can modify or delete the post, while a regular user can only view the post. How they work together in a real-world flow : Now we have the basic theoretical understanding of these two terms. how it can be implemented in Express.js.

Perhaps one of the most common tasks a Frontend Developer gets, is adding a button from time to time. It always sounds ridiculously simple, nothing can go wrong and it is always just a button. We need to add a button that... and days of work follow, integrations come in, migrations, state management. Yet, it is merely a button, how hard can it be to add one? Ironically this time it was me, who came up with the thought of adding a button. Any time a comment was made on a pull request, I had to copy the file path to open it in IDE to address or look it up. If I only had a button that does it, if I only had one...

On macOS, when switching scenes in OBS, if you move from a scene with a Display Capture source to one without it, macOS stops the screen capture session. When you switch back, the display stays frozen until you re-enable it in the source properties. The workaround is to include the Display Capture source in every scene, even the ones that don’t use it. Just hide it by clicking the eye icon or placing it below another layer. This keeps the capture session active and prevents interruptions when switching scenes. You may still encounter issues where the macOS Screen Capture source still keeps freezing and requires manual restarting in the properties of the source. The best (for now) fix for this is to use this script which will monitor the source and restart it if it's frozen. I have a Nix Flake setup here if you prefer that (or have to like me).  ( 6 min )

People often see the results of the books, the brands, the AI company, the magazine, the podcast, but very few know where it all began. It didn’t start with funding or connections.

Recent advancements in natural language processing have led to a groundbreaking discovery: a novel technique to detect subtle shifts in writer's tone and sentiment through the analysis of word embeddings' spatial relationships. This breakthrough has significant implications for sentiment analysis, opinion mining, and text classification tasks. The technique, built upon the foundations of word embeddings, such as Word2Vec and GloVe, involves representing words as points in a high-dimensional vector space. By analyzing the spatial relationships between these word embeddings, researchers can identify subtle patterns and trends in text data that reflect shifts in tone and sentiment. For instance, consider a text dataset containing reviews of a restaurant. By analyzing the word embeddings, researchers can identify clusters of words that are closely related in meaning, such as "delicious," "tasty," and "savory." These clusters can be visualized as points in the vector space, allowing re... This post was originally shared as an AI/ML insight.

The Hype Around Distributed Training: Unnecessary Redundancy in Models Despite its widespread adoption and touted benefits, I firmly believe that distributed training often overkills the model, leading to an explosion of redundant parameters that hinder performance rather than enhance it. 🤯 By pruning and fine-tuning locally trained models, we can achieve similar results with significantly reduced computational overhead, making them more efficient, scalable, and easier to maintain. The Problem with Distributed Training Distributed training distributes the workload across multiple machines, accelerating the training process. However, this comes at a cost. As models become larger and more complex, they tend to develop redundant parameters – weights that don't contribute significantly to the model's performance. These redundant parameters not only increase the model's size, but also its computational requirements, making it more challenging to deploy and maintain. **The Pow...

The Future of Large Language Models: Multimodal Input Prompts As we continue to push the boundaries of language understanding, it's clear that the traditional text-based input prompts used by large language models (LLMs) are no longer sufficient. By the end of 2026, I predict that a staggering 80% of LLMs will adopt multimodal input prompts, seamlessly integrating text, images, and audio to revolutionize the way we interact with AI. The Benefits of Multimodal Input Prompts This shift towards multimodal input prompts will lead to a significant average increase of 25% in context understanding and accuracy. By leveraging multiple sources of information, LLMs will be able to better comprehend nuances, emotions, and subtleties that are often lost in text-based interactions. Imagine being able to: Provide a photo of a scene and ask an LLM to describe it in detail, including emotions and actions Record a voice message and have the LLM transcribe it with high accuracy, while...

I stumbled upon one of its core ideas: Go doesn't have "async" programming (it has green threads—logical threads that handle concurrency via software through context switching). But Go is actually an asynchronous language by default! (It's comparable to every single function in Go using async/await.) The interesting part is that Go makes all the code look synchronous (but it handles the async parts where needed automatically).

Do you ever find yourself in a design or planning meeting with loads of talking heads, all confidently agreeing on important points, where it's almost like the conclusions are just a matter of fact and should be obvious to anyone? Yet you leave the meeting feeling unsettled, you sense gaps in the plan filled with vague arm wavey "someone will do something here" or a design that seems to hinge off a "decision engine" the details of which "we'll work out in the implementation." So you ask around a bit, but no one seems to actually be able to coherently explain what the fuzzy stuff will actually be, what it will do, or even who is doing it. "I need someone to paint me a picture to understand all this." you say to yourself. Well guess what, they probably won't. JFDI yourself, following these 2 rules: boxes shouldn't line up neatly labels should definitely have typos use crayons if your kids haven't pushed them up their nose It musn't be good looking Put your best interpretation of what the vague fuzzy stuff is into it. Even though you know you've got it wrong, just put it in. Then present it back, to everyone. If you are lucky, human nature will take over, an image that challenges a person's view seems to get much more of an immediate reaction than the written word. The "someone will do something here" was "my guys will sort this with a perl script in 2 days" to the ops manager, meanwhile the project manager was talking to a recruiter about getting 4 contractors in. It turns out the "decision engine" was assumed to be a 3 month procurement piece and integration with a SaaS offering to the product manager while one engineer had it down as 14 lines of code in an existing class. The slightly less confident conversations sparked are great. But the even better part is, having used crayons, no one will ever trust you with diagramming anything again and immediately someone else will take responsibility to draw your picture up in a "proper tool". Happy days  ( 7 min )

For a couple of months now, I've been on a mission to get immersed in a highly impactful open source project. As a student, getting into compilers has always been the kind of thing that sparked my interest — ever since building a programming language from scratch about a year ago, powered by LLVM and other somewhat esoteric dependencies like GNU Bison. I've been wanting to get into the trenches and see how production-level development is really done by the big companies. ClangIR was one of the projects that caught my attention. Here's a brief overview: ClangIR essentially aims to modernize Clang's well-established codegen pipeline by representing high-level semantics through its own dialect in MLIR. One of the main problems with the current state of the pipeline is that LLVM IR by itself i…  ( 13 min )

I just completed the Institute of Data / Michigan Tech Cybersecurity program, and for my capstone project, I scanned 22 random GitHub repositories with 4 secrets scanning tools. The results shocked me: 🚨 1,562 security findings across 22 repos 🔴 5 CRITICAL verified secrets (live API keys, active tokens) 🟠 579 HIGH severity issues (hardcoded credentials, weak crypto, injection flaws) 📊 Only 3.5% false positive rate But here's the real problem: I had to manually parse 4 different JSON formats, spend 3-4 hours aggregating results, and then map findings to compliance frameworks (OWASP, PCI DSS, NIST) by hand. Each one of those 5 critical secrets was a potential data breach waiting to happen. And most developers don't even know their secrets are exposed until it's too late. So I built a …  ( 10 min )

Why 90% of AI Apps Fail to Monetize Effectively—and How You Can Be the Exception with Monetization Strategies The landscape of AI applications is booming. Yet, despite the innovation and excitement, a staggering 90% of AI apps fail to monetize effectively. Why? Most lack clear monetization models that don’t disrupt user experience. Enter Monetzly—the first platform designed to help developers monetize their AI conversations seamlessly. As developers, we pour countless hours into creating applications that leverage cutting-edge AI technologies. However, the reality is that most monetization strategies—like subscriptions or paywalls—can alienate users, driving them away from your app. Monetzly offers a dual-earning model that enables developers to not only monetize their apps but also earn…  ( 7 min )

Personally, I'm a huge horror movie fan. At the first sign of the Fall season, I start my annual horror movie marathon. While I often get movie recommendations for my Halloween film binge, I rarely hear people talk about their favorite video games for spooky season. I've been a huge fan of the Resident Evil series ever since the Gamecube remakes of the early 00s. Sure, they're a bit campy and the story doesn't hold up to much scrutiny, but the early games really did define the survival horror genre, and there are some genuinely terrifying moments throughout the series. The 2019 remake of Resident Evil 2 is pretty flawless in my opinion, and a great introduction to anyone new to the series. A lesser known title but still a critical indie success, What Remains of Edith Finch is a whimsical…  ( 7 min )

liner notes: Professional : Pretty good day. Got my slides set up for my workshop tomorrow. Sat in on a meeting to discuss the documentation site. I only really just add information to the site, so it was cool to see the decisions on what goes where. Personal : Got a good version of a prototype printed and packaged. Looks pretty good. I also figured out how much I would charge the client to produce more. I also think I figured out how I want to make another possible product for the client so I researched some parts and placed an order. I also went through tracks for the radio show and put together the promo posts for the projects I picked up on Bandcamp. Going to finish putting together the radio show. I just remembered a slide I want to add for my workshop tomorrow, so I'll be adding that. I'm also going to iron some clothes because I'm going to a funeral for a friend. I also need to iron my company t-shirt and another shirt so I can change into my street clothes before the radio show. Not sure if I'll get the chance because I have to get up early to head out to the hackathon where I'll be giving a workshop, but I want to work on some sticker designs and maybe that new prototype idea. So yeah, radio show after the workshop at https://kNOwBETTERHIPHOP.com and no study session on Sunday because of the aforementioned funeral. Have a great night and weekend!

When you hear or read "Nation-state attackers", you can think of the worst. If you throw in fake Google ads and infostealers into the mix, then you might think: Who is safe?

After spending some time looking at the [Repomix] tool and looking for features to implement in my own [project], I found that there was a checkbox for removing comments from the final output. This seems like a useful feature to have, so I got to reading the code to find out how it was implemented. I decided to use AI to give me an overview of the code, then dived deeper on my own. The comment removal feature strips comments from source code files when packing a repository. For example: // This is a comment function hello() { /* Another comment */ return "Hello!"; } becomes: function hello() { return "Hello!"; } This reduces the token count when feeding code into LLMs, so it's definitely a useful feature to implement. removeComments is first defined in configSchema.ts as a boolean.…  ( 7 min )

The split between the mental models of local and shared state management in React apps has been around since time immemorial. Here's an example of how to do these conceptually similar things in a very similar way: + import { Store, useStore } from "@t8/react-store"; + + let counterStore = new Store(0); let Counter = () => { - let [counter, setCounter] = useState(0); + let [counter, setCounter] = useStore(counterStore); let handleClick = () => { setCounter(value => value + 1); }; return + {counter}; }; let ResetButton = () => { - let [, setCounter] = useState(0); + let [, setCounter] = useStore(counterStore, false); let handleClick = () => { setCounter(0); }; return ×; }; let App = () => {" "}; This is a full-fledged shared state setup. Similar handling of local and shared state means a short migration path from one to another without tedious refactors. More details on this package can be found in its concise overview.  ( 6 min )

When I got the task to test Delve.fun, I was genuinely curious. The platform is designed to make learning fun and interactive, and my goal was to make sure that the user experience matched that promise. It wasn’t just about finding bugs — it was about thinking like a real user while ensuring that everything worked as intended. 🔍 Getting Started Since Delve.fun is both a website and a mobile app, I tested it across desktop and mobile views to see how responsive and stable it was on different screens. 🪲 Reporting Bugs Some of the issues I found included: A missing or uninformative page title, which affected SEO and accessibility. An unsafe JavaScript evaluation warning in the console (potential security concern). Each issue was documented with screenshots and clear notes to make it easy for developers to reproduce and fix. 💡 What I Learned Combine manual exploration with automated testing tools effectively. 💬 Final Thoughts Working on this task for #HNGi13 has been such an eye-opening experience. It gave me hands-on exposure to real QA practices and helped me understand how small issues can have big impacts on users. I’m grateful for this opportunity and proud to have contributed to improving a product that focuses on learning and engagement. Big thanks to @HNGInternship for this learning journey — it’s definitely a step forward in my QA career.  ( 7 min )

MySQL is an open source relational database management system (RDBMS) that’s used to store and manage data. Its reliability, performance, scalability, and ease of use make MySQL a popular choice for developers. In fact, you’ll find it at the heart of demanding, high-traffic applications such as Facebook, Netflix, Uber, Airbnb, Shopify, and Booking.com. SQL, which stands for Structured Query Language, is a programming language that’s used to retrieve, update, delete, and otherwise manipulate data in relational databases. MySQL is officially pronounced “My ess-cue-el,” but “my sequel” is a common variation. As the name suggests, MySQL is a SQL-based relational database designed to store and manage structured data. In recent years, however, Oracle added additional support, including for the p…  ( 18 min )

Introduction Stripe is an online payment platform for securely accepting credit cards, bank transfers, and more. Stripe Checkout Sessions for one-time payments and a tamper-proof server webhook to confirm transactions. Terminology: "Payment Link" here refers to the URL returned by a Stripe Checkout Session (not Stripe's no-code "Payment Links" product). Client clicks "Pay Now". Backend creates a unique Checkout Session and returns the session URL. Client is redirected to Stripe, completes payment, and is redirected to your success URL. Stripe sends an asynchronous webhook (server-to-server) to your backend. Backend verifies the webhook signature, updates the database, and fulfills the order. Client gains access to the purchased resource. Client (browser) | | Click "Pay Now" v…  ( 8 min )

When AWS sneezed, the internet caught a cold. When AWS experienced its outage, it wasn’t just a small glitch in the cloud; it triggered a domino effect that rippled across much of the internet. The incident wasn’t caused by lost servers or faulty disks, it began with a failure in a monitoring system, the very component meant to keep everything running smoothly. Where it all started To understand the outage, it was important to grasp the role of DynamoDB within AWS. It wasn’t just another database instead it served as the data backbone that many AWS services depended on. Critical elements such as IAM session tokens, Service metadata, and Routing configurations were often stored in DynamoDB. So, when it began to slow down, AWS itself started to struggle. Although the outage originated from …  ( 11 min )

When OpenAI released Sora, their groundbreaking text-to-video AI model, content creators worldwide gained access to cinematic-quality video generation. But there was a catch—every video came with an embedded watermark. While this serves OpenAI's attribution and content tracking purposes, it creates a significant workflow friction for creators who need clean, production-ready videos. After seeing this gap in the market, I built SoraStrip—not just another watermark removal tool, but a developer-first platform with comprehensive API support, enterprise-grade reliability (99.9% uptime SLA), and webhook notifications for real-time processing updates. Here's the technical story behind it, the architectural decisions that set it apart, and why API accessibility matters in the AI video tooling eco…  ( 11 min )

In the first part of this guide, we walked through setting up Amazon EFS with Amazon EKS using Terraform — covering file system provisioning, IAM integration, and CSI driver configuration. And just after I thought we are back in business, one of the developers very proudly announce: This won't work for all of our apps; at least two of the apps need to share the same data directory. 🤪 Went back to the drawing board with one subtle challenge: How do we safely share the same EFS directory between multiple EKS applications while keeping our Terraform code clean, not over-engineered, declarative, and idempotent? Eventually came up with some ideas: This article shows how did we solve that precisely — using distinct EFS access points per unique path, rather than per app, here at Zenler. When mu…  ( 8 min )

Se você chegou aqui, já deve saber que o Arch Linux dá preferência para o banco de dados MariaDB ao invés do MySQL. Não entrarei no motivo disso (spoiler: a Oracle é uma matadora), porém, se quiser usar o MySQL, segue esse link. De qualquer forma, o MariaDB traz muitas vantagens para se usar, sendo seu principal fator de ela ser feita pelos mesmos criadores do MySQL. Ou seja, ao aprender MariaDB, indiretamente aprende-se a usar o MySQL, pois é praticamente a mesma coisa; só se diferenciam em casos muito específicos ou algo envolvendo o plano pago do MySQL. Dito tudo isso, vamos ao que interessa: Partindo do pressuposto que você use o arch,comece instalando o seu MariaDB,para isso vai no seu terminal e digite: yay -S mariadb #caso não tiver o yay sudo pacman -S mariadb Ao fazer isso,inicie o seu mariadb pelo terminal: sudo systemctl start mariadb sudo systemctl enable mariadb # Para iniciar automaticamente no boot Agora vai um dica bem interessante,sempre use um gerenciador de senha,pois agora vai precisar criar um usuario e senha com os seguintes comando: CREATE USER ' *usuario* '@' *localhost* ' IDENTIFIED BY ' *sua senha mega dificil* '; Aqui vale uma breve menção ao localhost,que ao meu vê,se você ira usa-lo só para projetos pessoais,recomendo usa,por ser seguro e pratico. Logo apos isso,passe o seguintes comando para ter permissão para criar,alterar e deletar tabelas: GRANT ALL PRIVILEGES ON *.* TO '*seu nome*'@'*localhost*' WITH GRANT OPTION; FLUSH PRIVILEGES; quit; Pronto! Agora seu servidor MariaDB está rodando e você já tem um usuário com permissões completas para começar seus projetos backend.  ( 6 min )

In this age of AI and vibe-coding, I still have a strong conviction that it is important to know the very basics of any programming language you would like to work with. How else can you 'vibe-code' if you do not even know what you are doing? That is exactly why I am creating this series titled JS FUNdamentals - a way for me to learn, share, grow and hopefully have some fun! I am very much in awe of the Javascript programming language (and really, any Front End development language or framework) because of the way it allows me to create magic 🪄 on a canvas. It has been the most exciting couple of months just learning to write code and building exciting projects that I have imagined. In this series, I will be writing about exciting concepts I come across in my learning journey to help solidify my understanding and also for anyone who stumbles on this blog looking for answers. This is for you and me. ✨ Stay curious and keep coding. Isioma.  ( 6 min )

You've heard the buzz: multithreading can dramatically improve your application's responsiveness and throughput, especially for I/O-bound tasks like web requests or file operations. You start a few threads, you watch your program fly. But then, the chaos begins. Your beautiful code starts behaving like a moody teenager, unpredictable, inconsistent, and occasionally flat-out wrong. The problem isn't your logic but it's a hidden culprit called a Race Condition. What exactly is a race condition in simple terms? A race condition occurs when the outcome of your program depends on the unpredictable timing of multiple threads accessing a shared resource. Imagine two people at separate ATMs trying to withdraw money from the same bank account at the exact same time. Without a proper mechanism to en…  ( 10 min )

If players can see each other's cards, strategies, and resources on-chain, you haven't built a game, you've built a public scoreboard. Web3 gaming promises ownership, fairness, and transparency. But there's a problem most developers don't talk about: complete transparency kills gameplay. When every move, resource, and strategy lives on a public blockchain, games lose the mystery, strategy, and surprise that make them fun. Here's why privacy matters for gaming, and how developers can build games that are both verifiable and actually playable. Traditional games rely on hidden information to create engaging experiences: Card games where you can't see opponents' hands Strategy games with fog of war and secret unit movements RPGs with hidden stats, surprise encounters, and secret quests Battl…  ( 8 min )

I believe Claude is one of the best tools for developers to quickly bootstrap new projects, brainstorm ideas, write content, and even debug tricky code. It's smart, intuitive, and great at helping you think through complex problems. But here's the thing: constantly switching browser tabs or juggling multiple windows just to use Claude can be distracting. As someone who spends hours coding, writing, or experimenting with AI tools, I wanted something cleaner - something that feels native. So I built Claude Desktop - a lightweight, fast, and unofficial desktop app for Claude AI. I love using Claude. But I also love focus. Having a dozen tabs open, each competing for attention, kills productivity. That's when I thought: What if I could have Claude sitting quietly on my desktop - ready whenever I need it - without the clutter of a browser? So I built one. Lightweight and Fast - Built with Electron, designed to stay out of your way. Seamless Claude Experience - Everything you love about Claude, right from your desktop. Distraction-Free Interface - Just you and Claude, nothing else. Secure by Design - No personal data is stored. Works Great on Linux - Now available officially on the Snap Store.

Have you ever wondered what actually happens when someone pays with Bitcoin or USDT on a website? Instead of banks and card issuers, these systems rely on wallet addresses, transaction hashes, and blockchain confirmations. Each payment is public, transparent, and irreversible.

Hello, I'm Maneshwar. I'm working on FreeDevTools online currently building *one place for all dev tools, cheat codes, and TLDRs* — a free, open-source hub where developers can quickly find and use tools without any hassle of searching all over the internet. Search is evolving fast. Traditional SEO — optimizing for Google’s blue links — is no longer the only game in town. Today, people ask AI chatbots, voice assistants, and generative engines for answers directly. That shift has given rise to three new terms: AEO (Answer Engine Optimization), GEO (Generative Engine Optimization), and LLMO (Large Language Model Optimization).

Recently, I was thinking about the transformation that has unfolded over the last few years in the business world, and something struck me deeply. Many businesses continue to operate with a pre-2020 mindset, clinging to outdated methods that are no longer effective. Before the COVID-19 pandemic, business was fairly predictable. If you had a shop, a signboard, and word of mouth, you could make sales. People walked in, bought what they needed, and left satisfied. Advertising meant printing flyers, running radio and TV ads, sharing business cards, or hanging a banner at a busy junction. Then 2020 came and everything changed. Don’t get me wrong, e-commerce platforms and online businesses existed before COVID. But the pandemic accelerated digital adoption in ways no one could have imagined. Sho…  ( 12 min )

Today I learned a new topic in Laravel — Laravel Pipeline.

'%'); }) ->when(isset($request->verify_status), function ($query) use ($request) { $query->where('verify_status', $request->verify_status); })->get(); The thing to notice here is that my data sources are different, but the rest of the processes are the same.

After months of building, documenting, and re-explaining the same boundaries, I realized something: That’s how Spec-Kit and OpenSpec were born — not from theory, but from exhaustion. This isn’t about artistic frustration — it’s infrastructure loss. That’s why I started developing my own libraries and system at bekalah.github.io/cathedral — to stop the cycle. Spec-Kit and OpenSpec exist to make authorship enforceable at the system level — not as a philosophical idea, but as a structural safeguard. The real challenge isn’t creativity. It’s endurance. So that’s what I’m doing: building libraries that teach sustainability through architecture. If I can get through the exhaustion long enough to stabilize it, the result will be something that runs cleanly — fewer wasted cycles, less manual repair- and not slipping into such exhaustion it causes actual physical illness.  ( 6 min )

If someone breached your server right now, would you even know? The faster you detect an intrusion, the faster you can stop it. In this post, we will walk through simple steps you can take to check for signs of unauthorized access and take immediate action - all within 60 seconds. Check out my Youtube Channel where I post all kinds of content accompanying my posts, including this video showing everything in this post. Step 1: See Who’s Logged In Run the following command to check who is currently logged in: who You should only see authorized users. If you spot a suspicious login, it might be time to investigate. See what’s running and sort by memory usage: ps aux --sort=-%mem | head Look for unfamiliar or suspicious processes. Malware often disguises itself with odd names or runs in the background silently. Identify listening services and active connections: ss -tulwn Check for unexpected open ports or connections to unknown IPs. Look at recent authentication attempts: tail -n 20 /var/log/auth.log Watch for failed login attempts or unusual root access events. On some systems, you might need to check: journalctl -xe | grep ssh sudo fail2ban-client status sshd Review which IPs have been banned and why. This helps track brute force attempts. If you’re using tools like AIDE or Tripwire, run an integrity scan to detect any unauthorized file changes: aide --check Speed matters. While these steps won’t replace a full intrusion detection system, they can help you spot threats early and react quickly. Want to go further? Set up automated alerts, enable two-factor authentication, and install Fail2Ban to actively block brute-force attacks. Thank you for reading this blog post.

Title: urllib – Python Standard Library for URL Handling Description: urllib is a built-in Python library that provides modules for working with URLs. It supports opening, reading, and parsing URLs, handling HTTP requests, encoding and decoding query strings, and working with internet resources. Since it’s part of the standard library, it’s commonly used for web scraping, downloading files, or interacting with web APIs without requiring third-party libraries. Installation: Example usage: from urllib import request, parse # Fetch content from a URL response = request.urlopen("https://www.example.com") html = response.read().decode('utf-8') print(html) # Encode query parameters params = {'q': 'python urllib'} query_string = parse.urlencode(params) url = f"https://www.google.com/search?{query_string}" print(url) PyPI page: standard library — no separate PyPI page https://github.com/python/cpython 3 Project Ideas: Build a simple web scraper to extract information from websites. Download images or files from a list of URLs. Create a small URL shortener or query string builder.  ( 6 min )

Hey devs , Lately, I’ve been thinking about how much we depend on AI tools — from generating code and writing documentation to designing UI mockups and even brainstorming new ideas. It’s amazing how fast these tools make us work, but here’s a thought: Are we trading original creativity for efficiency? When everything is optimized by algorithms, do we still challenge ourselves to think deeply, experiment wildly, and make mistakes — the things that actually lead to breakthroughs? I’ve noticed that some devs (myself included sometimes) lean on AI-generated code too heavily. Sure, it saves time, but it also feels like the “craft” part of coding is slowly fading. Others argue that AI just frees us to focus on the more meaningful parts of innovation. So I’d love to hear from you all: How do you balance using AI tools and keeping your creative problem-solving sharp? Do you think future developers will lose the skill of "manual" coding and design thinking? What’s one project where you consciously avoided AI assistance — and did it change how you think about creativity? Drop your thoughts below — I want to hear how you see the future of human creativity in an AI-driven world. Let’s make this a real discussion — not AI vs humans, but how both can push each other forward.  ( 6 min )

Given a string s, find the length of the longest substring without duplicate characters. example 1 Input: s = "abcabcbb" Output: 3 Explanation: The answer is "abc", with the length of 3. Note that "bca" and "cab" are also correct answers. Brute Force Approach: Initialize a variable maxLength to 0. Use a nested loop to generate every possible substring. The outer loop, with index i, defines the start of the substring. The inner loop, with index j, defines the end. For each substring, use a third loop or a hash set to check if it contains repeating characters. Create an empty set to store characters for the current substring. Iterate through the substring from i to j. For each character, check if it is already in the set. If it is, the substring has duplicates, so you can stop che…  ( 8 min )

Neste artigo damos continuidade à nossa análise histórica sobre os recursos que cada versão do Java trouxe para tornar o código mais limpo e simples para o desenvolvedor. Se você caiu de paraquedas aqui e ainda não leu a primeira parte, clique aqui. As versões Java 19 e 20 não trouxeram mudanças definitivas na forma de escrever código, mas apresentaram importantes recursos em preview que abririam o caminho para grandes transformações nas versões seguintes. O Java 21, lançado em setembro de 2023, esta versão trouxe finalmente recursos estáveis que mudaram a forma de escrever código no dia a dia. Entre eles estão: Record Patterns Pattern Matching for switch (Virtual Threads também foi finalizado, sem dúvida, a melhor parte desta verão. Virtual Threads merecem um artigo somente para elas.) Os Record Patterns permitem desconstruir objetos record diretamente em variáveis. record Point(int x, int y) {} // Before 21 // pattern matching for instanceof void printPoint(Object obj) { if (obj instanceof Point p) { System.out.println("x = " + p.x() + ", y = " + p.y()); } } // With 21 // record pattern void printPoint(Object obj) { if (obj instanceof Point(int x, int y)) { System.out.println("x = " + x + ", y = " + y); } } O Pattern Matching for switch foi finalizado no Java 21. switch você não precisa mais de instanceof verificar o tipo do objeto. // Before static String process(Object obj) { if (obj instanceof String s) { return "String com %d caracteres".formatted(s.length()); } else if (obj instanceof Integer i) { return "Número: " + i; } else { return "Outro tipo"; } } // With 21 static String process(Object obj) { return switch (obj) { case String s -> "String com %d caracteres".formatted(s.length()); case Integer i -> "Número: " + i; case null -> "Valor nulo"; default -> "Outro tipo"; }; }  ( 7 min )

Not even a month ago, I made a video about MistralOCR that many of you liked.  After that, a follower reached out with a problem they were having with an OCR Chatbot. I figured this was a common issue, so I decided to make a new video to help them and other developers. When documents contain complex tables, mathematical formulas, or multi-column layouts, traditional OCR tools often generate messy content that requires manual sorting. Then, just last week, I was browsing GitHub and came across Baidu's newly open-sourced PaddleOCR-VL-0.9B.  I'll be honest - when I saw it had only 0.9 billion parameters, my first thought was " Oh, another small model joining the fun?"

This blog is dedicated to arcaven, who initially made me aware of this observation and opened my eyes to the wild world of infrastructure and system operations patterns at scale. A few weeks ago, something clicked. Maybe the shorter, winter-approaching days slowed me down enough to notice, but suddenly threes were everywhere. Why do we split environments into development, staging, and production? Why do we stage upgrades across three clusters? Why do we run hot, warm, and cold storage tiers? Why does our CI/CD pipeline have build and test, staging deployment, and production deployment gates? The number three keeps showing up in systems work, and surprisingly few people talk about it explicitly. As it turns out, this pattern is not coincidence. It represents the intersection of distributed …  ( 9 min )

Participating in Hacktoberfest 2025 was an eye-opening experience that gave me a deeper appreciation for the open-source community. As a first-time contributor, I was initially nervous about navigating repositories, understanding issues, and submitting pull requests. But diving in taught me that open source is not just about writing code—it’s about collaboration, learning, and sharing knowledge. Through Hacktoberfest, I learned practical skills like forking repositories, branching, creating pull requests, and writing clear commit messages. Beyond the technical side, I experienced the value of community feedback and mentorship. Every accepted contribution, no matter how small, reinforced the idea that everyone can make a meaningful impact. This experience also changed my perspective on open source. I now see it as a living ecosystem where contributors and maintainers collectively improve software for the benefit of everyone. It’s a space where curiosity, persistence, and collaboration matter more than perfection. For anyone considering participating next year, my advice is simple: start small, pick issues that interest you, and don’t be afraid to ask questions. Open source is welcoming, and the learning and connections you gain are invaluable. Hacktoberfest is not just about the PRs—it’s about growth, contribution, and being part of something bigger.

When I started in web development, there was no division into frontend/backend/fullstack developers. Why BoltJS? I chose the second. BoltJS principles Example - TODO list Live demo Add Tasks todo: {{left}} of {{count}} function TodoForm(self) { self.todo = ""; self.add = () => { if (!self.todo) { alert("TODO can not be empty."); return; } self.emit("new-todo", self.todo); self.todo = ""; } } function TodoList(self) {…  ( 7 min )

My Hacktoberfest 2025 Experience This Hacktoberfest has been an incredible journey of learning, collaboration, and growth. As a participant, I got the opportunity to explore open-source projects, contribute to real-world codebases, and connect with developers around the globe. I started by exploring beginner-friendly issues in various repositories Initially, it felt a bit intimidating — understanding someone else’s code, setting up repositories, and making meaningful contributions wasn’t easy. But step by step, I learned how to fork projects, create branches, submit pull requests, and even write clear commit messages. One of the highlights for me was contributing to projects in multiple programming languages and seeing my code being merged. Each accepted pull request gave a sense of achievement and motivation to do more. I also learned the importance of clear communication in pull requests and how even small contributions can make a difference. Apart from coding, Hacktoberfest helped me improve my GitHub workflow, understand collaborative development practices, and gain confidence in open-source contributions. Sharing a video explanation of my projects on LinkedIn and linking my GitHub repo was a new experience that helped me document my learning journey.I have worked on Python ,awesome-go,,axios, transformers, excalidraw, app-ideas, free-programming-books. Overall, Hacktoberfest 2025 has been both challenging and rewarding. It strengthened my technical skills, boosted my confidence, and introduced me to a supportive community of developers. I’m excited to continue contributing to open source beyond Hacktoberfest! This is a submission for the 2025 Hacktoberfest Writing Challenge: Contribution Chronicles  ( 6 min )

In the world of web development, the smallest snippets of code often have the biggest impact. One of the most overlooked yet powerful components of a webpage is the meta tag. To the average user, meta tags are invisible. But to search engines, social platforms, and browsers, they’re essential signposts that describe, categorize, and index your site. For developers and technical SEOs, understanding how meta tags work — and how to implement them effectively — is key to improving visibility, performance, and user experience. What Are Meta Tags? Meta tags are snippets of HTML code placed inside the section of a webpage. They provide metadata — data about data — that describes the content of the page. While they don’t appear directly in the page’s content, they communicate critical informati…  ( 8 min )

Welcome to the first lesson! Okay so for the first one, I’m going to combine the two lessons in the “Git Basics” section of The Odin Project. The first one was more of the lesson on explaining what it is and why it’s important, while the second one was an assignment to apply what you learned as well as learn the common terminal Git commands. First off, what the fuck is Git? Good question! It’s essentially a save button on steroids. See, a normal save button on a text doc just overwrites the file. You only have the current version. If you wanted to see what you wrote two days ago, you’d have to have saved a separate copy, like My-Document-v2-FINAL-actually-final-v3.doc. It’s a mess. Git is different. It keeps track of every single save (or “commit”) you make, across multiple files and folde…  ( 9 min )

Ever feel like a simple “target player” doesn’t exist anymore? That’s because, well, they don’t. Between 2015 and 2025, gaming stopped being a niche and became... everything. Everyone. Your mom. Your coworker. That kid on a tablet. For developers, this isn’t just trivia. It’s the map. Understanding who’s playing where (and why) helps you design smarter, market better, and avoid building for a shrinking segment. Let’s dig into what actually is changing. In 2015, the industry was still mostly “core.” You had PC enthusiasts, console loyalists, and the early stirrings of mobile. Monetization leaned on premium sales and DLC. Mobile was big in Asia, but Western devs often brushed it off as “casual.” (A mistake, in hindsight.) Metric 2015 Notes Global Players (Billions) 2.03 Mostly PC/co…  ( 9 min )

My name is Jeffrey Payne, and I’ve wanted to be a software engineer ever since I was in elementary school. I took my first coding class at the Apple Store when they were participating in the “Hour of Code” movement by Code.org, and I took Computer Science classes all through middle and high school. I even went to college for Information Science and Arts at the University of Arizona and was part of the group that won first place in the app development category of our senior showcase. While it sounds like I should know how to build an app from the ground up or create an API, I don’t. My main goal in those classes was just to pass, to get a grade good enough that I wouldn’t fall behind or end up on academic probation, risking my financial aid. Because of this, I focused more on “keeping up” t…  ( 8 min )

Unlocking AI's Inner Voice: Simulating Personalized Cognition Tired of generic AI responses? Imagine training an AI to think and express itself with the unique flair of a particular individual. What if we could build AI agents that truly understand and reflect specific cognitive styles? That's the promise of individualized cognitive simulation (ICS). At its core, ICS is about building computational models that approximate the individual thought processes. By representing cognitive features – like preferred linguistic patterns and conceptual associations – we can nudge large language models (LLMs) towards unique outputs. Think of it like this: an actor preparing for a role. They don't just memorize lines; they inhabit the character's mind, influencing their delivery and interactions. We'r…  ( 7 min )

Introduction Both Microsoft Recall and Rewind AI are designed to help you "go back in time" on your computer, letting you recall anything you've seen, said, or done. But while both share the same goal, they take very different approaches to privacy, availability, and implementation. In this post, we'll break down how these two tools compare and which one might be right for you. Microsoft Recall is an AI-powered feature introduced in Windows 11 Copilot+ PCs. It continuously takes automatic screenshots every few seconds and stores them locally on your computer. These snapshots are analyzed with on device AI, allowing users to search past activities using natural language, like: "Find the chart I saw during the meeting last Thursday" or "Show me the document I was editing before lunch."

You ever wake up one fine morning and think — “Hey, what if I could make one file that’s both a picture and an executable?” Yeah… me too. And that, my friend, was the beginning of my descent into the binary abyss — The Great PNG + EXE Polyglot Experiment. 🌀 The dream was simple: “What if I could merge a .png image and a .exe file so the file behaves like a normal picture and runs as a program?” Sounds magical, right? Like a hacker-magician pulling hidden code out of an innocent photo. ✨ First thing I learned: file formats are divas. do not like sharing space. A .png starts with this signature (magic bytes): 89 50 4E 47 0D 0A 1A 0A While an .exe begins like this: 4D 5A Both want to be at the very start of the file — and neither likes to compromise.

Versão em Português Building a Shopify POS UI Extension is a great way to add custom features to your Shopify POS. You use the Shopify CLI, generate your extension, customize the React component, and everything seems to work fine... until you need to make that one fetch call to your backend. At this point, the following questions might come up: How can my backend know this request is legitimate? How does it know which shop this call is coming from without exposing that data in the request? How can we prevent someone malicious from pretending to be our extension and sending fake data? If you've ever faced this, you know the answer is JWT authentication. Shopify solves this elegantly using Session Tokens. The official documentation shows the way, but it can be a bit abstract.

If you’ve worked with Symfony, you’ve used symfony/http-client. You’ve run $client->request(‘GET’, …) and $response->toArray(). This is the bread and butter of API consumption, and it works beautifully for simple use cases. But modern applications aren’t simple. They’re distributed, asynchronous, and expected to be resilient. What happens when you need to: Fetch 100 API endpoints without waiting 30 seconds? Consume a 500MB JSON file without hitting your memory limit? Handle an API that flakes out and retries automatically? Protect your app from a failing downstream service? Manage OAuth2 tokens that expire every 60 minutes? This is where “trivial” usage ends. The HttpClient component is one of the most powerful and layered components in the Symfony ecosystem. It’s designed to solve these e…  ( 15 min )

Free vs Paid Football APIs: Choosing the right option for your project That brings you to a big question: should you use a free football API or go straight for a paid one? It’s not just about cost, as your choice affects league coverage, data speed, scalability, and ultimately how users experience your app. In order to choose between a free vs paid solution, it helps to first understand exactly what a “football API” is and how it works. A football API (Application Programming Interface) is essentially a software service that gives you structured access to football-data (fixtures, scores, players, teams, stats, etc) through predefined requests and responses. In more familiar terms: it’s the bridge between raw sports-data and the application you’re building. Here’s a simplified breakdown of …  ( 15 min )

Introduction Every modern web app has to connect a client (browser, mobile app, desktop app) to a server. Why? To do things like: Check if a user is logged in. Get their subscription status. Update their profile picture. Process a payment. These requests are how applications feel “alive”, the client asks the server for information, and the server responds. Two common ways to make those requests are: HTTP APIs (like REST or GraphQL). Remote Procedure Calls (RPC). At first glance, they both look similar: you send data and get data back. But their design philosophy and developer experience are quite different. Let’s walk through both, with real-world examples. HTTP (HyperText Transfer Protocol) is the language of the web. It works by thinking in resources (nouns), each exposed at a URL. Exa…  ( 8 min )

If you’re a technical writer who’s ever tried to get meaningful input from developers, you probably know it can be… challenging. Developers are focused on solving complex technical problems, not on writing pages of documentation. And yet, without their input, creating accurate and user-friendly docs is nearly impossible. So, how can writers and developers find common ground? Let’s explore practical ways to make this collaboration productive and even enjoyable for both sides. Developers often see documentation as something secondary to “real work.” Their primary focus is writing and optimizing code, fixing bugs, and shipping new features. In fast-paced agile environments, the top priority is a working product — not the documents that describe it. Add to that tight deadlines, constant task s…  ( 8 min )

A technical deep-dive on the architecture of modern data quality systems Your pipeline reports success. Schema validation passes. Record counts match. NULL constraints hold. Yet your downstream systems are making decisions on garbage data. This isn't a monitoring failure—it's an architectural blind spot. Traditional data quality systems validate structure while semantic correctness goes unchecked. The cost? Financial institutions lose an average of $15 million annually to poor data quality, with Citibank facing $536 million in fines between 2020-2024 for inadequate data governance. Most systems stop at Layer 2. They catch type errors and statistical outliers but miss semantic invalidity—data that is structurally perfect but contextually wrong. Traditional data quality platforms follow an …  ( 11 min )

I’ve been navigating the world of Linux long enough to know that debates over systemd can get pretty heated. It’s like stepping into a family dinner where everyone’s trying to convince Grandma why her famous casserole recipe should be replaced with something trendy. This time, it’s the Debian Technical Committee (DTC) making headlines by overriding a proposed change to systemd. I couldn’t help but dive into this topic because, quite frankly, it’s a classic case of open-source community dynamics and how they reflect broader tech trends. For those who aren’t knee-deep in Debian discussions, systemd is the init system that manages system processes after booting. It’s powerful, but it’s also controversial. In my experience, it’s one of those tools that folks either love or hate—kind of like pi…  ( 8 min )

It feels like everyone’s racing to adopt artificial intelligence these days. If you’re a managing partner, you probably feel that pressure too. But honestly, diving into AI without really understanding what you’re getting into? That’s a recipe for headaches. Before you make any moves, you’ve gotta know what data your AI will see and how that impacts client confidentiality. This isn’t just some IT detail—it’s about your firm’s reputation and the trust you’ve built with clients. It’s also worth asking: who’s actually watching over the AI?

I was implementing a signup endpoint for an API where users can register via email. There are many ways to verify an email address. You could use a popular library like go-playground/validator to check if the input is in an email format. However, this doesn't confirm if the email address actually exists or if its domain can receive mail. If you prefer not to use regex or an external package, Go's standard library offers the net/mail package to validate an email address format. This approach is generally better than a simple regex validation because mail.ParseAddress parses an address according to the official RFC 5322 specification, which defines the standard for email format. Basic Format Validation Let's start by checking if a string has a valid email format. Example 1: A Well-Formatte…  ( 9 min )

Java Delete Files: Your Ultimate Guide to Cleaning Up the Digital Mess Let's be real. In the world of programming, we're often so focused on the fancy stuff—the complex algorithms, the sleek UIs, the powerful databases—that we forget about the digital janitor work. You know, cleaning up the files your application creates, modifies, and then... just leaves behind. If you're building anything substantial in Java, from a simple data logger to a full-blown enterprise system, you will need to delete files. And doing it right is more than just calling a delete() method. Do it wrong, and you'll face cryptic errors, locked files, or worse, accidentally nuke the wrong stuff. So, let's break it down. This isn't your average, dry textbook tutorial. This is a practical, no-fluff guide on how to dele…  ( 11 min )

Introduction If your project is like others, you’ll probably have a util.h and util.c files containing general utility functions. For example, suppose you want a function strnspn that’s like strspn() except limits the number of characters checked to n: size_t strnspn( char const *s, char const *charset, size_t n ); For such fundamental functions, you want to ensure they work correctly in all cases, including degenerate cases, so that if your program has a bug, you can reasonably rule out the bug being in one of those functions. To do that, you need to write unit tests for them. In order to write unit tests, a small framework is helpful. Yes, I’m aware of this: Specifically, there are several open-source, unit-test frameworks for C and they’re probably good; but I wanted something ex…  ( 8 min )

In today’s digital-first economy, no organization is too small to attract cybercriminals. In fact, small and medium-sized enterprises (SMEs) have become the most frequent victims of attacks simply because they lack the strong, layered cybersecurity for small businesses that large corporations can afford. Hackers look for easy targets — companies with weak defenses, minimal security awareness, and outdated systems. Protecting your organization requires understanding how attackers strike and how you can build cybersecurity for small businesses that’s both practical and effective. Hackers are profit-driven opportunists. They realize that smaller businesses store valuable data — customer details, payment information, and credentials — yet often skip serious investment in cybersecurity for smal…  ( 9 min )

As developers, we build systems based on logic, efficiency, and targeted outcomes. We wouldn't write a function that just randomly tries to solve a problem; we define inputs, processes, and expected outputs. Yet, when it comes to growing a B2B tech product, many companies still use a marketing approach that feels like a UDP broadcast—fire and forget, hoping some packets land. What if we could apply an engineer's mindset to marketing and sales? What if we treated it like a targeted, stateful protocol? That's Account-Based Marketing (ABM). It's not just marketing jargon; it's a strategic algorithm for B2B growth, and it's built on principles developers understand: data, personalization, and automation. Traditional B2B marketing is a funnel. You cast a wide net (blogs, ads) to catch as many l…  ( 9 min )

Plus, regulators also raised the stakes. So this shows, your customers expect certainty from you. They want to know where the money is, who touched it, and why it paused. And you need that view as well, because blind spots create losses and fines. But nothing to worry, end-to-end payment tracking changes that. Because it comes with features like full traceability, which shows the route, timestamps, fees, FX, and reason codes. It also shows exceptions in real time, so you can act before fraud spreads or a filing deadline passes. This is why financial leaders embed tracking into a cross-border pa…  ( 8 min )

We all love strategy. Funnel diagrams. PLG loops. Growth hacks. But after building Indie10k — my “growth gym” for indie devs — I realized something uncomfortable: strategy doesn’t matter if you don’t show up every day. When I started Indie10k, I thought success meant finding the right playbook. I studied frameworks, copied funnels, and tweaked pricing models for weeks. None of it moved the needle. Why? Because growth doesn’t come from knowing the path — it comes from walking it. What actually worked was simple: One rep. Every day. A small action: write a post, fix an onboarding bug, or talk to one user. Each rep gave me data. The data gave me clarity. And clarity made strategy obvious. That’s when I learned: Strategy is a compass. Practice is the engine. You can’t steer a car that isn’t moving. If you’re building your first (or fifth) SaaS, don’t chase perfect strategy. Chase momentum. Because momentum compounds. One rep turns into a streak. A streak turns into insight. Insight turns into growth. That’s how every “overnight success” actually happens — one boring, consistent day at a time. Do one rep — something small but repeatable. Ship. Share. Learn. Repeat. Your strategy will get sharper the longer you stay in motion.  ( 6 min )

I’ve lost count of how many side projects I’ve built that never found users. Beautiful landing pages. Clever names. Clean code. But no demand. Every indie hacker goes through that phase — building in excitement, then watching the numbers stay at zero. These days, I do the opposite. Before I build anything, I test if people actually want it. That mindset led me to create JoinWaitlist.dev — a tiny tool that helps founders launch a waitlist page in minutes to validate their idea before writing a single line of code.

What is Prompt Engineering? By 2025, AI tools like ChatGPT have become household names. With the widespread availability of large language models (LLMs), many people assume that interacting with these models is as simple as typing a question. However, there's more to it. Prompt engineering is the skill of crafting the right input, in a way that helps the AI model generate more accurate, relevant, and useful responses. If we don't know how to talk to these models, their responses can become vague or irrelevant. Learning prompt engineering ensures we can tap into the full potential of AI. LLMs, like ChatGPT, Google’s Gemini, and others, are trained on massive datasets containing text from various sources. These models don’t "understand" the way humans do, but they excel at predicting the …  ( 12 min )

As the agent-economy advances, the need for a common infrastructure becomes critical. ERC-8004 presents a lightweight yet powerful standard to coordinate autonomous agents across chain boundaries. It doesn’t prescribe detailed logic—but provides the minimum primitives needed so individual projects can build differentiated solutions. It’s a proposed standard that defines three on-chain registries – Identity, Reputation & Validation – to support discovery and interaction of autonomous agents in a permissionless context. Identity registry: Gives each agent a unique ID, address, and domain pointer; capabilities are stored off-chain for flexibility. Reputation registry: Enables agents to authorize clients to leave feedback; the onchain events provide an audit trail while the data sits offchai…  ( 7 min )

Introduction While developing React, I had the opportunity to use key={JSON.stringify(filters)} in a component, so I'd like to summarize it here. JSON.stringify() is a JavaScript function that converts objects and arrays to strings. const user = { name: "calros", age: 20 }; const json = JSON.stringify(user); console.log(json); // → '{"name":"calros","age":20}' The object is converted to a JSON-formatted string. JSON.stringify() is a function for safely handling objects as strings. In JavaScript, it's often not possible to store or send data as is. Converting data to a string using JSON.stringify() can be useful in a variety of situations.  ( 6 min )

I. Introduction / Motivation The fundamental job of this layer is to convert the network layer's datagrams into frames, the data unit specific to Layer 2. A frame consists of the original datagram plus the Link Layer header (containing MAC addresses) and the trailer (containing error-checking information). Key Services of the Link Layer: Framing: It encapsulates the network-layer datagram with a Layer 2 header and a trailer, creating the final frame. Frame boundaries are essential for the receiver to identify where a data unit begins and ends. Link Access: It specifies the rules for accessing the shared transmission medium (like an Ethernet cable), which is critical when multiple devices share one connection. This is handled by Media Access Control (MAC) protocols. Addressing: It uses M…  ( 11 min )

In Oracle, PL/SQL packages can maintain a session-level state. This means that once a package is loaded into a user session, its global variables retain values across multiple calls. In previous Oracle versions, when a package was recompiled, all active sessions holding that package’s state would encounter ORA-04068 errors. In Oracle 26ai, the RESETTABLE clause introduces a new way to manage PL/SQL package states more safely and efficiently. To understand how it works, let’s examine the following practical scenario. First, we create a simple package with a global variable and a procedure that increments and prints its value: CREATE OR REPLACE PACKAGE my_pkg AS Glob_cnt number := 0; PROCEDURE prc_inc_cnt; END my_pkg; / Package created CREATE OR REPLACE PACKAGE BODY my_pkg AS PROCEDUR…  ( 7 min )

The custom-built chip has proven to be an essential tool for researchers and developers alike, driving advancements in areas like natural language processing, computer vision, and recommendation systems. For those new to the world of AI hardware, let's quickly break down what TPUs are. Developed by Google, TPUs are Application-Specific Integrated Circuits (ASICs) specifically designed for machine learning tasks. They were first introduced in 2017 as a way to accelerate deep learning computations and have since become an industry standard. …  ( 7 min )

It’s October 2025 and it’s my first time vibe coding. I have mixed feelings. Frankly, when vibe coding tools came out I was very skeptical. Don't get me wrong, I like using LLMs and I've gotten so used to GitHub Copilot just completing my thoughts in VSCode and Vim. But generating entire code bases with LLMs? I'm not so sure about that. Then from time to time, I looked at code from Lovable, Repl.it, and Cursor that my friends had sent me. I wasn't impressed. It was full of redundancies. It wasn't elegant. It was code that's fine for a beginner, someone making their first strides at building products, not someone I would let touch an actual production code base. Also for context, here at Metorial we build infrastructure that's capable of running tens of thousands of MCP servers concurrently…  ( 10 min )

The first time I fired up Android Studio, I thought I was in over my head. XML files everywhere, red squiggly errors I didn’t understand, and settings that felt like the cockpit of an airplane. I just wanted to build a simple to-do app. Instead, I spent a week Googling error messages and hopping between random tutorials. Spoiler: I never finished that app. A few years later, things were different. This time, I had a proper course guiding me step by step. I learned Kotlin the right way, understood Android Studio’s quirks, and built apps that connected to real APIs. Eventually, I shipped my first app to the Play Store. The difference wasn’t more time—it was structure. If you’re starting in 2026, Android is still the world’s most widely used operating system, powering billions of devices. But…  ( 9 min )

Java Architecture defines how the Java programming language works internally — from writing code to running it on any device. “Write Once, Run Anywhere” (WORA) 2. Main Components of Java Architecture Java Architecture mainly consists of three key parts: A. Java Virtual Machine (JVM) JVM is the engine that runs Java programs. It converts bytecode (intermediate code) into machine code for the current operating system. It makes Java platform-independent. Functions of JVM: Loads code Verifies code Executes code Manages memory (Garbage Collection) B. Java Runtime Environment (JRE) JRE = JVM + Libraries + Other components to run applications. It provides all the necessary runtime environments for Java programs. Think of JRE as: run a Java program (but not to develop one). C. Java Develop…  ( 6 min )

Leaks in the memory are the silent murderers of the application performance. They cause the user experience to get ever slower and, in extreme situations, make your app crash. In the realms of React Native, where the code of your application is run in a thread of JavaScript and communicates with native threads, memory management and understanding are essential. To any React Native app development firm, these problems need to be detected and resolved as part of launching a quality product. In case you have an event listener in a component, such as a keyboard event or a notification triggering the entire application, then you should unsubscribe from it upon removing the component. Otherwise, the component that has disappeared will remain in the memory of the listener, and it will not be eras…  ( 8 min )

Testing is often the bottleneck in delivering reliable web apps at speed. As apps grow in complexity, with different front-end frameworks, microservices back ends, varying devices, networks, and usage patterns, traditional testing approaches, like manual QA and basic automation, struggle to keep up. Cross-browser testing combined with AI and advanced automation, is turning that around. Let’s break down what’s changing, how, and where we’re headed. Before jumping into what’s new, let’s acknowledge the challenges: Test explosion: With multiple browsers, device types, screen sizes, locales, and network conditions, the number of test permutations is massive. Flakiness and maintenance: UI tests often break when minor changes like CSS, layout, or IDs occur. Lack of coverage for non-functional di…  ( 9 min )

Olá, dev! 👋 Se você está mergulhando no mundo do Java e já se perguntou o que exatamente é uma interface, este post é pra você. Vamos quebrar tudo em partes simples — sem enrolação — e entender por que as interfaces são tão poderosas e essenciais pra quem quer escrever código limpo, escalável e bem estruturado. Em poucas palavras, uma interface é um modelo (ou contrato) que uma classe se compromete a seguir. Pense assim: ela define o que uma classe deve fazer, mas não como isso deve ser feito. Quando uma classe “assina esse contrato”, ou seja, implementa uma interface, ela precisa cumprir todas as promessas definidas ali — implementando cada método que a interface declara. A interface especifica obrigações — o que uma classe deve ter. A classe garante a implementação — como ela v…  ( 8 min )

When you’re developing software, designing interfaces, or building embedded systems, your display isn’t just a piece of hardware — it’s your window into the project. Choosing the right display panel can directly affect how you perceive colors, contrast, and overall clarity. Among the different LCD technologies available today, IPS displays have become the industry favorite. But what makes them so special? And why do engineers, developers, and designers prefer them over TN or VA panels? Let’s break it down from a technical yet practical perspective. Most modern LCDs (Liquid Crystal Displays) fall into three main categories: Panel Type Viewing Angle Color Accuracy Contrast Response Time Typical Use TN (Twisted Nematic) Narrow Low Medium Fast Gaming monitors, budget devices VA (Verti…  ( 8 min )

We killed our micro-frontend project last quarter. Here’s why 👇 We didn’t make the call lightly. We had sunk months into splitting our React monolith, wiring up module federation, and selling leadership on “independent deployments.” But after living with it, the cost outweighed the benefit. This isn’t a manifesto against micro-frontends — just an honest post-mortem of what went sideways for us. Back in 2023, our team was buzzing with excitement 🚀. Micro-frontends promised autonomy, speed, and scalability. We pitched it, got buy-in, and started migrating. Fast forward months later: Our pipelines multiplied ⚙️. Debugging felt like digging through digital archaeology 🕵️. UI drift turned our product into a patchwork quilt 🎨. Lesson: Micro-frontends didn’t fail because the id…  ( 10 min )

The Model Context Protocol (MCP) defines an architecture where a central language model (agent) can securely interact with various external functions (tools) and resources. In the context of AI coding assistants, these tools might range from code refactoring services to internal repository accessors. The MCP is designed to standardize the agent-tool communication flow, including the sharing of tool descriptions and context. However, this reliance on external tools creates new attack surfaces. This article focuses on two primary methods attackers use to compromise the system: Data Poisoning and Prompt Injection. Data Poisoning targets the integrity of the tools themselves or the model's environment, while Prompt Injection exploits the language model's reliance on contextual instructions to…  ( 11 min )

I'm Done With Data Preprocessing Nightmares in RAG Applications Background When I started working on RAG projects last year, the first challenge I faced wasn't choosing the right model or vector database. It was something much more fundamental: How do I convert various document formats into data that AI can actually use? Tables in PDFs wouldn't parse correctly. Word documents came out as a formatting mess. OCR results from scanned documents were hit-or-miss at best. After testing numerous open-source tools, I found they either handled only a single format or required writing tons of glue code to connect different tools together. The situation got even worse when our company required on-premise deployment—no sending documents to third-party APIs. We had multiple GPUs available,…  ( 10 min )

Unlock Guitar Soloing Secrets: A Graph Engine Approach Stuck in the same old guitar riffs? Feeling lost when improvising over chord changes? Many guitarists struggle to break free from scale-based playing and truly connect their solos to the underlying harmony. But what if you could effortlessly generate solos that perfectly complement any chord progression? The secret lies in a clever application of graph theory. Imagine representing each chord's essential notes (chord tones) as interconnected nodes in a network. By strategically mapping the relationships between these notes across a chord progression, we can unlock fluid and musically satisfying soloing possibilities. This approach utilizes a graph engine to calculate optimal note transitions between consecutive chords. The engine find…  ( 7 min )

While the world's leading artificial intelligence companies race to build ever-larger models, betting billions that scale alone will unlock artificial general intelligence, a researcher at one of the industry's most secretive and valuable startups delivered a pointed challenge to that orthodoxy this week: The path forward isn't about training bigger — it's about learning better.

You stand at the peak of JavaScript mastery. Your Node.js applications are optimized, your architectures are sound, and your async/await patterns are poetry. Yet, sometimes, you feel a constraint—a gentle, persistent hum from the V8 engine, reminding you that for all its power, it is still a virtual machine.

Integrating with a legacy C++ library that holds your company's secret sauce. Interfacing directly with hardware or system-level APIs. When you hit this wall, you have a choice. You can try to work around it in JavaScript, or you can descend a layer deeper. You can step into the Forge and craft a Native Addon. This is not a journey for …  ( 10 min )

The Conductor's Baton: Orchestrating Real-Time UIs with Turbo Streams There is a profound silence in the space between a user's action and the application's response. For years, we've filled that silence with JavaScript. A click happens, we fetch(), we get JSON, we painstakingly .innerHTML, we update state, we handle errors. We have become carpenters, hammering individual pieces of the DOM into place, one event at a time. But what if we've been speaking the wrong language? What if the browser doesn't need a detailed blueprint, but a simple, direct command? "Update this." "Append that." "Remove this other thing." Welcome to Turbo Streams. This isn't just another technique; it's a philosophical shift. It's the moment we stop being carpenters and become conductors. Our Rails backend is no lon…  ( 10 min )

If you’ve ever played around with ChatGPT or any large language model, you might’ve heard the word “token” thrown around — usually when someone talks about limits or pricing. But what exactly are tokens? Think of tokens as the smallest pieces of text an AI understands. They’re not always full words — sometimes just parts of them. “ChatGPT is awesome!” The model doesn’t actually “see” sentences the way we do. It sees a long chain of these tokens and tries to predict what comes next — that’s how it builds responses. Why does it matter? Because: Tokens decide how long your input or output can be (there’s always a token limit). Tokens also determine cost — AI tools charge based on how many tokens you use. And finally, they define context — the more tokens the model can process, the more it can “remember” in a conversation. In short, tokens are like the currency of understanding in the AI world. Every question, answer, and word you type is made up of them. Fun fact: the latest GPT models can handle over 128,000 tokens at once — roughly the length of a full novel. Imagine an AI reading an entire book and still remembering every detail — that’s the power of tokens.  ( 6 min )

AI won’t replace QA — but QAs who use AI will replace those who don’t. 💬 Why this matters A few years ago, “AI in testing” sounded futuristic. As a QA Lead, I see a clear difference between testers who leverage AI and those who ignore it. And honestly — when we hire new QAs, I always pay attention to how candidates talk about AI. 🧠 1. Prompting as a core QA skill Prompting is basically asking better questions — but to AI. Why it matters: 1. Generate test cases from user stories 2. Translate acceptance criteria into concrete scenarios 3. Explore “what if” or edge cases quickly Example prompt: “Act as a senior QA. Generate 10 edge-case test scenarios for a signup form with CAPTCHA and rate-limiting.” 🪄 Tip: Always use context. Don’t just ask “generate test cases” — tell the AI what envi…  ( 8 min )

Decision Trees Evolved: Faster, Smarter Reinforcement Learning Imagine a self-driving car hesitating at a complex intersection or a robotic arm fumbling with a delicate task. Complex AI making suboptimal decisions? Current reinforcement learning often struggles to deliver both optimal performance and easily understandable decision-making, especially as problem complexity grows. What if we could unlock clear, high-performing policies with a radical speed boost? At its heart, this involves finding the best if-then-else structure, essentially a decision tree, that guides an agent through different states to maximize rewards. Optimizing decision trees within a dynamic environment is traditionally computationally expensive. The breakthrough lies in reframing the tree's construction as a very…  ( 7 min )

The Border Gateway Protocol serves as the Internet's primary routing mechanism, operating through interconnected relationships between network devices. At the core of BGP functionality lies the concept of peering relationships, where routers establish connections to share routing data across different networks. These BGP peer connections determine how internet traffic flows globally, affecting everything from connection speed to network costs. Effective monitoring of these peer relationships requires understanding session stability, route exchanges, and potential security vulnerabilities. Network operators must implement comprehensive monitoring strategies that go beyond basic connectivity checks to ensure optimal performance and detect issues before they impact users.

You’ve prompted your large language model, a powerhouse of digital intelligence, to perform a task so simple a child could do it: “Write a short poem and save it to my desktop as poem.txt.” The AI obliges, composing a beautiful stanza in seconds. It presents the text to you in a pristine, ephemeral output window. You copy it, open a text editor, paste the content, and save the file yourself. The AI, for all its cognitive might, remains trapped behind the glass of its application, unable to touch your actual computer. This is the frustrating paradox of modern AI assistants. They possess immense knowledge but lack basic agency. They can reason about your file system but can't interact with it. They are brilliant minds suspended in a digital void.

Part 2 - Structure and Composition Read Part 1 here. API-Led Connectivity is a proven architectural pattern for separating data, business logic, and representations across APIs. Numerous articles have been written about its advantages, but putting them into practice often raises many questions. We looked at the basics in Part 1. A System API should only connect to one System of Record. A System API is meant to be a clean layer of abstraction over a single data source. This one-to-one relationship makes your architecture clearer and more flexible: Focus and simplicity: the API clearly shows a single source, which makes it easier to understand where data comes from and how it is structured. Reusability and stability: APIs that are linked to one SoR are easier to version, reuse, and change…  ( 12 min )

Artificial Intelligence isn’t just changing how we work — it’s also transforming how we protect and attack. In 2025, AI has become both a digital bodyguard and a double-edged sword for freelancers and small businesses. Let’s unpack the tools that can safeguard your systems — and the ones cybercriminals are now using against you. AI-driven security tools are becoming smarter and faster than ever. They detect unusual patterns, block suspicious activity, and even learn from past attacks. Here are a few worth keeping on your radar: Tools like Darktrace and Cylance use machine learning to study your normal network behavior. When something unusual happens — like a massive data upload at 2 a.m. — they instantly flag or block it. AI filters in Microsoft Defender and Proofpoint now identify phis…  ( 7 min )

Read our original blog here We rebuilt onboarding around our MCP (Model‑Context‑Protocol) integration so developers start inside their editor with our SDK—not a detour through example apps or sandboxes. Early results: ~3× more users reach SDK install versus our previous flow, and they see real product value sooner. This piece shares why we made the change, how the MCP‑centered flow works, what we learned, and what’s next. Our north star for onboarding has always been simple: get users to the “aha” moment fast. With a SDK‑based product, that “aha” usually requires installing the SDK into the user’s own app—and that’s exactly where friction creeps in. We had invested heavily in a guided tutorial with three flavors: No‑code, in‑browser walkthrough Code sandbox to see real code without install…  ( 10 min )

If you use JavaScript, just remove the types where necessary. The Core Route Files Dynamic Routing Typescript Helpers To define routes in Next.js, we use file-system based routing, which mean we use files and folders from within our app. When installing the Next.js app using: npx create-next-app@latest Next.js will create a folder app. You can safely delete everything inside it to remove the noise. This is of course not necessary, but I recommend doing it just to see every file in action without those boilerplate code from Next.js.…  ( 11 min )

If you’ve ever heard that “Java supports only single inheritance”, you might think Java is limited compared to languages like C++ that allow multiple inheritance. But the truth is... Java gives you the best of both worlds — simplicity and flexibility — without the messy diamond problems. Let’s break it down 👇 🧩 What Is Inheritance in Java? Inheritance allows one class to acquire the properties and behaviors (fields and methods) of another. It’s one of the core pillars of Object-Oriented Programming (OOP). class Animal { void eat() { System.out.println("Eating..."); } } class Dog extends Animal { void bark() { System.out.println("Barking..."); } } public class Main { public static void main(String[] args) { Dog d = new Dog(); d.eat(); …  ( 7 min )

One of the cool things about the way we've architected Hypertune is that experiments aren't something you reference directly in your code. Instead, they're created in the Hypertune dashboard and inserted into the rollout logic of a feature flag. Many teams manage feature flags and experiments separately, often using different systems for each. As a result, they end up with separate “experiment flags.” When testing a new feature, that means checking two flags in code: Your main feature flag — to control rollout to internal users, beta testers, etc. Your experiment flag — to split traffic between variants. At first, this might seem reasonable. But it quickly introduces complexity — and risk. In theory, the experiment flag should only be checked if the main flag is true. A user should only en…  ( 7 min )

I’ve always loved both maths and coding, but I never found a space where the two truly merge. So I decided to build one myself: MathHacks. It’s a weekend “mathathon” where participants build creative maths-based projects — visualisations, puzzles, small tools, or any idea that blends maths and creativity. Think of it as a hackathon, but for maths. The first MathHacks starts in 8 days and it’s completely free and open to everyone — students, developers, or anyone who enjoys problem-solving. Why I built it: I wanted a place to experiment with maths in a fun, hands-on way. I wanted something that feels creative, not competitive. I wanted a small, community-driven space for maths + coding lovers. If that sounds like your kind of weekend, come join in at the first mathathon I’d love to see what you come up with!  ( 6 min )

Introduction I found a way to avoid the well-known problem where “infinite scroll resets after a browser back,” using a modal that combines Next.js App Router’s Intercepting Routes and Parallel Routes. Even after using the browser back action, the scroll position of the infinite list is preserved. You can try it yourself with this demo app. This is a Next.js framework–specific approach, but I hope it helps anyone who is facing—or has faced—this problem. Notes This post does not explain the low-level details of Intercepting Routes or Parallel Routes. The main goal is to convey how the app feels when infinite scroll is combined with a URL-addressable modal built with Intercepting + Parallel Routes, via the demo app. The context is a web application, not a native app. Infinite scroll UIs h…  ( 10 min )

​FastAPI is getting more and more popular, as is building agents. Developers building agentic systems are starting to turn to FastAPI as one of the more ergonomic web frameworks for building endpoints and then adding on a Model Context Protocol (MCP) layer so that AI agents can discover and invoke those endpoints as “tools”. For example, with FastAPI-MCP you can take an existing FastAPI application, attach mcp = FastApiMCP(app) and mcp.mount(), and your endpoints become usable by an LLM-based agent with minimal extra work. But when it comes time to deploy your agent, how should you go about it? TL;DR: Heroku is great to start, but you pay for convenience with higher tiers, less control, and platform lock‑in. Defang keeps the Heroku‑like workflow but deploys your FastAPI app into yo…  ( 9 min )

In modern data workflows, APIs are everywhere — powering everything from model inference to data extraction. Yet, handling API failures gracefully is often neglected by data scientists, who tend to focus on analysis and modeling while treating fault tolerance as a “software engineering problem.” However, failure handling is not just an engineering nicety — it’s what makes a data pipeline resilient, automated, and production-ready. When your data pipeline processes hundreds or thousands of files via APIs, a single timeout or upload error can halt the entire process. You depend on external systems — their uptime, latency, and error messages are outside your control. Failures aren’t binary — some require retries, others should be skipped or gracefully degraded.

If you’ve ever watched your site slow down under traffic or worse—collapse during a peak moment—you’ve felt the sting of inadequate performance testing. But what kind of test would have saved you? Load or stress? And why does it matter? This isn’t just a definition battle. It’s about making the right calls across your dev, QA, and SRE teams.

It's about surgically removing the influence of specific data points or connections in a graph neural network (GNN) without drastically impacting the model's overall performance or requiring a complete retraining.

Getting data from modern websites is not the same as it used to be- today, most websites render their data dynamically making it hard for traditional web scrapping tools to obtain any data. In this project: The Africa Energy project, we are going to use different tools to obtain data about Energy Indicators across 54 African countries for the years 2000 - 2022 from the The Africa Energy Portal. The project features: a web scrapper that extracts JSON data from API network responses. The Africa Energy Portal is a dynamic webpage that contains information about energy indicators across 54 African countries. The indicators are energy access, supply and technical aspects related to energy. The indicators are further broken down into sub-sectors such as 'Population access to electricity-National' which shows the percentage of people with access to electricity on a national level etc. The project uses the following technologies: a. Python for developing the web scrapping logic The scrapper utilizes Selenium to automate browser interaction such as loading the page and selecting all required themes, years and countries for precise data extraction. The scrapper obtains all the selected fields of the data ie; id, name, score, unit, region name, indicator topic, indicator source, indicator name, indicator group, year, url The data is extracted in JSON format and appended to an empty list before it is flattened and converted to csv format. Working on this project has been nothing short of a learning experience from the thought process of understanding the project, to learning of different ways to execute the project, to implementation of the same.

VM 在不關機的情況下, 就算應用程式更新版本, 舊process 仍然可以持續執行, 直到程式結束或timeout; 而佈署在k8s 的應用程式單位是pod, 交由k8s 代為管理, 當pod 因任何因素需要被關閉時, process 面臨仍然在執行, 但宿主(即將) 停止的窘境 先快速且抽象地說, 便是讓process 將任務處理完/交接, 再讓它離開 1. 將收到payload 寫回關聯式資料庫 2. 發送付款成功事件(e.g. pub/sub) 3.

Given the announcement of "The Future of Lodash", with Lodash joining OpenJS, I thought I'd express my ongoing love for Lodash and share one of the many reasons why it is still useful for me day-to-day. TL;DR Merge is an unsung hero of the library. In the absence of something like Immer, if you need to immutably update a deeply-nested object, you can do this: const properties = { /* ... */ }; setTracks((prev) => ({ ...prev, [trackId]: { ...prev[trackId], points: { ...prev[trackId].points, [pointId]: { ...prev[trackId].points[pointId], properties: { ...prev[trackId].points[pointId].properties, ...properties, } } } } })); Or you can do this: setTracks((prev) => merge({}, prev, {[routeId]: {points: {[pointId]: {properties}}}})) );  ( 6 min )

I didn’t set out to join a fandom. I played a game. I enjoyed it. That was supposed to be the end of it. But then I finished the second episode of Dispatch by Adhoc Studio and sat there, still in the glow of it, and realized something was pulling at me. A kind of emotional inertia. Yes, the writing was immaculate, yes the mechanics were smoothly executed. But more than that, I cared. About my decisions, about the characters and...I wanted to talk about them. I wanted to know what other people saw in them. I wanted to laugh at the same dumb lines and ache at the same quiet moments That’s when it clicked: this is what makes someone a fan. Not how many hours you’ve logged or how much merch you own. Just this: you care so much that the silence after the credits rolls feels too loud. And the …  ( 7 min )

If you’ve ever pushed a bug to production (and who hasn’t?), you know that cold sweat moment when an error alert hits your Slack at 2 AM. Debugging in production isn’t like fixing code on your laptop — there’s pressure, limited visibility, and real users depending on you. But with the right mindset and tools, you can handle it without breaking more things. Let’s walk through a safe and strategic way to fix production issues — step by step. Your logs are your first line of truth. Before touching the code or restarting anything, observe what’s actually happening. ✅ Tips: Filter logs by request ID, timestamp, or user session. Look for error patterns — repeating exceptions, failed API calls, or database connection errors. Avoid drowning in noise: focus on recently changed modules. …  ( 7 min )

Task 2: Array Formation The Task You are given two lists: @source and @target. Write a script to see if you can build the exact @target by putting these smaller lists from @source together in some order. You cannot break apart or change the order inside any of the smaller lists in @source. Example 1: Input: @source=([2,3], [1], [4]), @target=(1, 2, 3, 4) Output: true Use in the order: [1], [2,3], [4] Example 2: Input: @source=([1,3], [2,4]), @target=(1, 2, 3, 4) Output: false Example 3: Input: @source=([9,1], [5,8], [2]), @target=(5, 8, 2, 9, 1) Output: true Use in the order: [5,8], [2], [9,1] Example 4: Input: @source=([1], [3]), @target=(1, 2, 3) Output: false Missing number: 2 Example 5: Input: @source=([7,4,6]), @target=(7, 4, 6) Output: true Use in the or…  ( 9 min )

I released @acoolhq/react-tiny-store. It is a small external store that works with useSyncExternalStore, is hydration-safe, and keeps re-renders scoped with selectors. npm i @acoolhq/react-tiny-store I needed something between raw Context and a full-blown state library. Context + reducers made unrelated components re-render whenever a big object changed, and pulling in Redux/Zustand felt like overkill for a few shared slices. You want fine-grained renders without heavy setup. You have a few shared slices and don’t want a large framework. You care about SSR correctness with minimal API surface. A full-featured global state framework with time-travel and middleware. It’s a small, practical layer for the 80% case. Selector-based reads so only affected components re-render Works with SSR hydr…  ( 7 min )

TL;DR Hybrid work is here to stay, but thriving in it requires a deliberate mix of technology, culture, and soft‑skill development. This guide walks you through the current hybrid landscape, shows how to build a robust communication framework, cultivates trust, aligns productivity processes, and highlights practical ways to upskill your team—including a quick look at tools like softskillz.ai for targeted coaching. When the pandemic forced many companies to go fully remote, most organizations discovered that a binary “office vs. home” model was too limiting. The hybrid work model—where employees split time between a physical office and remote locations—offers flexibility, broader talent pools, and often higher employee satisfaction. Yet it also introduces friction points: misaligned expec…  ( 12 min )

Why Interoperability Matters in Healthcare? For example, a patient visits a primary care doctor, is referred to a specialist, goes in and out of lab visits, and then winds up in the emergency room. Each provider collects information. But if their systems do not talk to each other, important information can be overlooked. That can result in repeated tests, delayed diagnoses, or even dangerous errors. EHR, LIS), smart connected devices, and the user interfaces for patients and medical staff.(Source: ScienceSoft) Improved decisions around care: Physicians can view their full patient history instead of fragmented bits.

The concept of the T-shaped engineer isn't new. It's been around, quietly championed by forward-thinking tech leaders and organizations. But in 2025, as LLMs transform how we build software, this professional archetype has evolved from "nice to have" to essential. Picture the letter T. The horizontal bar represents breadth - a working knowledge across a wide range of technologies, methodologies, and domains. The vertical stem represents depth - expert-level mastery in one or a few specific areas. A T-shaped engineer might have deep expertise in distributed systems architecture while maintaining conversational fluency in frontend frameworks, DevOps practices, data engineering, and security principles.

I recently attended GOTO conference in Copenhagen (https://gotocph.com/2025, you can find the slides for some of the presentations there) and would like to share some of the interesting topics. This is about organisations, but I think it has even wider application. There are 2 types of organisations which differ only by the answer to the question: are people bad or good? These 2 approaches can be seen in my opinion everywhere when there is a group of people which need to follow any rules. This can be for example how the city authorities deal with passengers as far as transportation is concerned. However, the forest is rare. There are also quite many desert people who like the yellow and in fact most of the organisations are like Sahara. I think the key is just to realize these 2 landscapes exist and know which one suites you best to be able to work effectively. https://tidyfirst.substack.com/p/forest-and-desert https://martinfowler.com/bliki/ForestAndDesert.html  ( 6 min )

Last month I was joking with a friend about possibly traveling to Bali in December. I didn’t search it, didn’t message anyone about it, and didn’t even type the word “Bali” anywhere on my phone. And yet — the next day my Instagram Reels were full of Bali travel videos. Coincidence? Or does Instagram secretly listen to us through our phones? This question — “Is Instagram listening to me?” — pops up in conversations everywhere. The short answer: almost certainly not in the way people imagine.

The concept of autonomous agents, software that can operate, transact, and make decisions on-chain without constant human supervision has been around for a while. However, widespread adoption has been hampered by incompatible frameworks, isolated registries, and trust assumptions. ERC-8004 is a proposed Ethereum standard designed to address these challenges by providing a minimal yet extensible framework for agent discovery and trustless interaction. The standard defines three core registries: Identity: Assigns each agent a unique ID and links it to off-chain metadata describing capabilities, supported protocols, and domains. Reputation: Creates an on-chain audit trail of client-authorized feedback, enabling reputation tracking without storing all data on-chain. Validation: Supports task …  ( 7 min )

A Usabilidade para além do Front-end Quando falamos em "usabilidade", é quase automático pensarmos em interfaces bonitas, botões no lugar certo e telas que respondem rapidamente. Em resumo: a experiência do usuário final. Mas e se eu disser que a usabilidade é um conceito que deveria ser aplicado muito antes do front-end? Que ela começa no coração do sistema: o back-end. Um back-end com boa usabilidade não é sobre ter uma "interface gráfica bonita" (afinal, o "usuário" aqui é, na maioria das vezes, outro desenvolvedor ou sistema). É sobre criar uma experiência fluida, intuitiva e eficiente para quem vai consumir, manter e expandir o seu código. Pense no back-end como a cozinha de um restaurante.

But I thought I'd put together a Quickfire article about it to help spread the word, for anyone (such as those new to PHP) who may not be aware of it. match Expression in PHP The match expression allows you to compare a value against multiple conditions and return a given result (although a result doesn't necessarily have to be returned). It's similar to a switch statement in the sense that you can define "branches" based on different conditions. However, a key difference is that the match expression uses strict comparison (===), whereas a switch statement uses loose comparison (==). This means that with match, the types of…  ( 10 min )

Today I finally understood what makes React so powerful — state. Once you realize that your UI is just a reflection of state, React suddenly clicks. I created a small component that shows three steps: Learn React ⚛️ Apply for jobs 💼 Invest your new income 🤑 It includes “Next” and “Previous” buttons to move through steps, and a close button to hide the section. useState, I learned how to control what appears on screen based on the component’s state. Update State Based on Current State When updating a value using its previous value, always pass a function to the setter: setStep((s) => s + 1); That ensures React always uses the latest version of state — even with multiple updates. One Component = One State Every component has its own state — completely independent from others. UI as a Function of State The best way to think about React is: 🖥️ UI = f(state) Whenever your state changes, React re-renders the UI to match. When to Use State Use useState for data that should change over time or control the UI, like: Whether a modal is open Which step the user is on A toggle or input field If a value doesn’t affect what the user sees, use a normal variable instead — not state. 👉 Use state for anything dynamic. Understanding state changed the way I see React. thinking in terms of state transitions. Now, every time I build something dynamic, I ask myself: “How should my component look when this piece of state changes?” And that’s when React truly starts to feel alive. ⚡ I’ll keep experimenting with multiple states in one component and later explore Context and Reducers to manage complex state.  ( 7 min )

In previous posts, I’ve introduced some of the key syntax and features of Turbine, a Markdown-inspired scripting language. out parameter, a mechanism for returning multiple values from a function, similar to how C and C++ handle it. In Turbine, a function can only have one return value. But sometimes, you want to return a main result and an additional status flag, for example, when you want to detect division by zero in a divide() function. Many scripting languages, such as Python, can easily return multiple values using tuples: def divide(a, b): if b == 0: return 0, False return a / b, True result, ok = divide(10, 2) That’s convenient and expressive. references or pointers to return additional results: int divide(int a, int b, bool &ok) { if (b == 0) { ok = f…  ( 8 min )

Developers spend just 1.4% of their time using VS Code's debugger - most rely on console.log statements instead. 68 developers tracked over 3 months (July-October 2025) 11,805 coding sessions (30-minute intervals) averaging 18 minutes of active coding each 3,526 hours of active coding time analyzed (excluding idle time) All data collected via FlouState automatic tracking Building FlouState solo meant debugging felt like half the job. Those late-night sessions hunting down edge cases were exhausting - terminal full of console.log() statements, manually reproducing bugs, reading stack traces. After 3 months (203 hours tracked), I looked at my own data and saw something surprising: I spent 0.2% of my time using VS C…  ( 10 min )

In my previous posts in the series, I described an AI Scoring Agent prototype that was designed to score open-ended student responses using a scoring guide. While the agent performed well in some cases, my last post outlined a number of ways in which it fell short. This final post is written more from my educator perspective, and shares my lessons learned about AI in student assessment. Although this has shown that AI agents should NOT score student assessments, I also share some new directions in which this type of tool could be appropriate and helpful. This was highlighted in my last post, so I will not repeat the evidence here. I am admittedly an AI skeptic in regards to education, so this lesson is not at all surprising to me. Hallucinations generated by the LLM are the biggest concern…  ( 11 min )

They don’t tell you this in bootcamp, but coding is basically emotional damage with syntax. 😅 One minute you’re like: “I’m a genius — I just solved a bug!” And the next minute you’re like: “Why is this semicolon ruining my entire life?” Let’s be real — we’ve all been there. Coding isn’t just about logic, it’s about emotional resilience. You’re not just building software — you’re building character. 😂 Here’s the truth nobody says out loud: Even the best developers Google the same question five times a day. We all copy-paste from Stack Overflow like it’s a sacred ritual. We all say “just one last test” 47 times before pushing to production. But here’s the beauty in it — Coding teaches you how to keep trying even when nothing works. It teaches you patience, problem-solving, and humility. And sometimes… it teaches you new swear words. 💀 So if you’re feeling stuck or frustrated, remember — every great developer once broke down over a missing bracket. The difference between junior and senior isn’t how much they know — it’s how calmly they panic. 😎 💬 What’s your funniest “coding meltdown” moment? Drop it below — let’s laugh (and cry) together. 👇  ( 6 min )

Welcome back to Day 3 of our DSA Problem Series, where we explore one problem each day, understand its logic, and break it down into clean Java code. Today’s challenge is a classic stack-based problem — Problem Statement Given an array of integers, for every element, find the next greater element that appears to its right. Example: Input: [ 4, 5, 2, 10, 8 ] Output: [ 5, 10, 10, -1, -1 ] Explanation: For 4, next greater is 5 For 5, next greater is 10 For 2, next greater is 10 For 10, no greater element → -1 For 8, no greater element → -1 Brute Force Thought A straightforward approach would be: For each element, look to its right until you find a greater number.

Are your files and folders missing after you run the newly created image? This is a common issue when building images with Packer. It is a widely used tool for creating machine images in a repeatable and automated way. When using the QEMU builder to generate local or CI-friendly images, it's common to upload files with the file provisioner and configure systems using shell provisioner. One often overlooked but critical part of this workflow is how the virtual machine shuts down after provisioning. Without a proper shutdown, the resulting image can be unstable, incomplete, or even unbootable. graceful shutdowns matter. After provisioning completes, Packer snapshots the virtual disk to produce the final image. If the guest operating system is not properly shut down before this snapshot, yo…  ( 7 min )

Introduction In cloud environments, organizations often segment their IT infrastructure into multiple virtual networks (VNets) for better security, performance, and management. For instance, a company may separate core IT services such as DNS and security from departmental workloads like manufacturing or R&D. However, in many cases, applications and services across these networks still need to communicate securely for example, when a manufacturing app needs to access a shared DNS or authentication service hosted in the core network. This is where Azure Intersite Connectivity comes in. By implementing Virtual Network Peering, you can connect multiple VNets in Azure, allowing traffic to flow privately through Microsoft’s backbone network without requiring VPNs or gateways. In this hands-on…  ( 8 min )

Every click, swipe, and voice command that feeds into artificial intelligence systems passes through human hands first. Behind the polished interfaces of ChatGPT, autonomous vehicles, and facial recognition systems lies an invisible workforce of millions—data annotation workers scattered across the Global South who label, categorise, and clean the raw information that makes machine learning possible. These digital labourers, earning as little as $1 per hour, work in conditions that would make Victorian factory owners blush. These workers make 'responsible AI' possible, yet their exploitation makes a mockery of the very ethics the industry proclaims.

Introduction In the part 1 we introduced our sample application. We basically used AWS Lambda Functions like GetProductByIdHandler where we extended io.micronaut.function.aws.MicronautRequestHandler and injected DynamoProductDao and other services by using Jakarta EE jakarta.inject.Inject annotation. While this is a valid approach, sometimes you have existing Micronaut REST application which runs on containers or servers, and you'd like to port it to Serverless with as little effort as possible. As we use here DynamoDB we're locked-in, so it's more about making our application portable between AWS services like EC2, ECS (also with Fargate), EKS (also with Fargate) and Lambda. Of course, you can replace DynamoDB repository layer with RDS, Aurora, Aurora Serverless or newly released Aurora…  ( 12 min )

Unlocking AI: The Simplicity Revolution in Reinforcement Learning Tired of reinforcement learning (RL) models that feel like black boxes? Do you dream of AI that not only performs well but also explains why it made a particular decision? Current RL approaches often involve complex neural networks, making it tough to understand their logic and adapt them to new situations. Imagine you want to teach an AI to navigate a complex maze. Traditionally, this meant training a neural network for countless iterations, with little insight into the strategy it was developing. A new approach uses decision trees directly as policies. This leads to interpretable rules, like "if the corridor is clear, move forward, else check for an opening to the left". Optimizing these tree-based policies efficiently, …  ( 7 min )

Welcome to Day 12 of the #80DaysOfChallenges journey! After chasing the longest word in a sentence on Day 8, today's challenge, finding the longest word without using len(), took things to a new level. This beginner-friendly task pushed me to rethink a familiar problem, diving deeper into manual counting, loops, and logic. It's like solving the same puzzle but with a twist that forces you to understand the gears behind Python's built-in tools. The goal was to find the longest word in a user-provided sentence, but with a catch: we can't use Python's len() function to count characters. Instead, we manually count each word's characters using loops, returning both the longest word and its length as a tuple. This challenge was a fantastic exercise in manual iteration, string manipulation, and l…  ( 10 min )

Email is still a crucial communication medium for companies, but it also ranks among the top platforms targeted by cybercriminals. Scams such as phishing, spoofing, and business email compromise (BEC) lead to financial losses in the billions for businesses annually. To combat these risks, implementing email authentication protocols like DMARC has become vital for safeguarding domain reputation and ensuring trustworthiness. DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is a protocol designed to help domain owners stop unauthorized usage of their email domains. It operates by confirming whether an email that appears to originate from a specific domain is actually sent by authorized servers. If the verification fails, the email can either be rejected…  ( 8 min )

I'm currently working on a software designed more than a decade ago. It offers a plugin architecture: you can develop a plugin whose lifecycle is handled by the software. The tough part, though, is how you access the platform capabilities: via static methods on singletons. @Override public boolean start() { var aService = AService.getInstance(); var anotherService = AnotherService.getInstance(); // Do something with the services var result = ...; return result; } There's no easy way to test the start() method. In the old days, Mockito developers had pushed back against this feature, and the only alternative was PowerMock. The decision was reversed in 2020 with the 3.4.0 release, which introduced static method mocking in Mockito. I liked the previous situation better. M…  ( 7 min )

An exception is an unwanted or unexpected event that occurs during the execution of a program (i.e., at runtime) and disrupts the normal flow of the application. Java Exception Handling is a way to detect, handle, and recover from unwanted or unexpected events (exceptions) that occur during the execution of a program. It allows the program to deal with runtime errors gracefully, without crashing, by providing alternative flows or meaningful error messages. Example: Imagine you’re using a food delivery app. You place an order, but your internet disconnects for a moment. Instead of crashing, the app shows a message: "No Internet Connection. Please try again." This is possible because of exception handling. The app catches the error and shows a friendly message instead of terminating . An…  ( 9 min )

After seeing an example on cassidoo's site, I decided to add an "AI Transparency" page to my site as well. Both she and the post she links make a really good point about how, if a person or company is transparent about how they use AI, it helps us trust that their work is more authentic in general. They recommend adding a page to your site (e.g. /ai) that details how you make use of generative AI (or not). From the simplest "No posts on this site are written with generative AI," to a longer, more detailed breakdown, the idea is not to cover your bases with legalese, but to be authentic, clear, and real. It's not a bad thing to use AI, necessarily. It's a tool like any other, and a user needs to understand how it works--pro's, con's, strengths, and dangers. But it's good to be open about it to help people understand and gain context for your work. And if you do decide to add one to your site, you can add your site to this public database of /ai page-having sites!  ( 6 min )

The supervisor agent can call a tool called researcher, which returns: A plain-English diagnostic summary (research text) The sources it consulted (citations) The exact places in the diagnostic summary where each source should be cited (citation placement) The original text snippets pulled from each source for the citation (verbatim quoted text) Once the troubleshooter tool finishes its job and hands off to the the main agent (or supervisor), it needs to: Analyse that information to either ask the user follow-up questions or suggest next steps, But it must do this in a way that: When supervisor responds it should include proper inline citations tied to the right parts of the explanation from the research i…  ( 8 min )

Three years ago, I started the Japanese Property Price Forecasting project to analyze and predict second-hand apartment prices in Japan. It was a great learning experience, but like many early projects, it lacked a structured pipeline and modern machine learning best practices. Recently, I revisited the notebook and modernized the workflow. Here’s what I added and improved. Previously, the notebook handled categorical and numeric features manually. Now, it uses a full scikit-learn Pipeline to cleanly separate numeric and categorical preprocessing: Numeric features: imputation with mean + standard scaling Categorical features: imputation + one-hot encoding (handling unknown categories safely) This makes the workflow cleaner, easier to maintain, and fully reproducible. Instead of a simple regression, the updated notebook uses LightGBM with hyperparameter tuning. This allows the model to achieve better performance while keeping the training process efficient. Old column names had spaces and special characters, which could cause issues with pipelines. All columns are now sanitized (_ instead of spaces and symbols), making the notebook pipeline-friendly and more robust for experimentation. The notebook now loads CSVs dynamically, making it easy to handle multiple files without hardcoding paths. Updating old projects is a great way to apply what you’ve learned over time. In this case: Cleaner, maintainable code Better reproducibility Stronger model performance Ready for future extensions (feature engineering, explainability, or deployment) You can explore the updated notebook here: Japanese_Property_Price_Forecasting_v2.ipynb If you’re curious about structured ML pipelines or modernizing legacy notebooks, this is a small but practical example of the process.  ( 6 min )

Introduction Hello everyone. My name is K.H. and I'm currently studying at a local university in Vancouver, Canada. Executing git push and automatic deployment (cd) I learned how to deploy a Django app to AWS EC2. I built a scalable configuration using Auto Scaling Groups and a Load Balancer. I used the stress command to apply CPU load and confirmed autoscaling operation. I learned basic configuration and monitoring methods for stable app operation in a cloud environment. I learned how to process form input with Django and dynamically generate results with Python. I was able to implement basic Python logic, including conditional branching, numerical calculations, and string manipulation. I understood the flow of data between Django views, templates, and forms.

In any large organization, managing user identities is a constant challenge of balancing security with user convenience. For an enterprise-grade workflow orchestration platform like Apache DolphinScheduler, robust and flexible authentication is not just a feature-it's a necessity. Previously, DolphinScheduler offered several login options, including Password, LDAP, and Casdoor SSO. However, these methods had limitations, such as a high dependency on the Casdoor project or an inflexible OAuth implementation, making it challenging to integrate with diverse enterprise identity systems. As my Google Summer of Code 2025 project, I'm excited to introduce the solution: a that streamlines and modernizes access to DolphinScheduler, making it truly enterprise-ready.

One of the biggest obstacles for call centers to manage customer experience is noise. Agents working in hybrid or remote environments battle barking dogs, keyboard clicks, and street chatter that disrupts professionalism and clarity. The AI noise cancellation for call centers helps remove background noise, improving voice fluency, and ensuring every interaction sounds calm, confident, and human. Industry estimates suggest that poor audio quality can increase average handle time (AHT) by 15–20%, as agents and customers repeatedly ask for clarification. When calls become frustrating, customer satisfaction (CSAT) scores drop—and even skilled agents struggle to sound composed. For QA teams, reviewing noisy recordings wastes analysis time and lowers scoring accuracy. That’s why modern contact…  ( 9 min )

When you start learning backend development, it’s easy to focus on features, getting APIs to respond, connecting to the database, or just making it all work. In my projects built with FastAPI, I follow a simple but consistent pattern for error handling. For Example: from fastapi import APIRouter from sqlalchemy.exc import SQLAlchemyError from app.logger import logger # custom logger from app.database import get_db from app.models import Student router = APIRouter() @router.get("/students/{student_id}") def get_student(student_id: int): try: db = get_db() student = db.query(Student).filter(Student.id == student_id).first() if not student: logger.warning(f"No student found with ID {student_id}") return {"error": "Student not found"} logger.info(f"Fetched student: {student.name}") return {"student": student.name, "email": student.email} except SQLAlchemyError as e: logger.error(f"Database error while fetching student {student_id}: {e}") return {"error": "Database connection failed"} except Exception as e: logger.error(f"Unexpected error in get_student API: {e}") return {"error": "Something went wrong, please try again later"} Here’s what’s really happening behind the scenes: Every error is caught from database issues to unexpected runtime exceptions. Logs are categorized info for successful events, warnings for missing data, and errors for critical issues. No internal crash leaks to the user. Instead, users see a clean, friendly response while I get detailed error traces in my logs. The logger I use writes all messages to a local file, but also integrates with CloudWatch for live monitoring when deployed. It’s one of those invisible systems that keeps everything steady. Over time, I’ve learned that a stable backend isn’t the one that never fails it’s the one that knows how to fail gracefully and tell you exactly why.  ( 7 min )

Python bytearray Overview bytearray is an important built-in class in Python that represents a mutable sequence of bytes. bytearray is similar to bytes, but unlike bytes, bytearray is mutable. # Create a bytearray ba = bytearray(b'Hello') print(ba) # Output: bytearray(b'Hello') print(type(ba)) # Output: ba1 = bytearray(b'Hello') print(ba1) # bytearray(b'Hello') ba2 = bytearray('Hello', 'utf-8') print(ba2) # bytearray(b'Hello') ba3 = bytearray(5) print(ba3) # bytearray(b'\x00\x00\x00\x00\x00') ba4 = bytearray([65, 66, 67, 68]) # ASCII: A, B, C, D print(ba4) # bytearray(b'ABCD') # bytes is immutable (will cause error) b = b'Hello' # b[0] = 74 # TypeError: 'bytes' object does not support item assignment # bytearray is mutable ba = bytearray(b'Hello') ba[0] = 74 # ASCII code for 'J' print(ba) # bytearray(b'Jello') ba = bytearray(b'Hello') ba.append(33) # ASCII code for '!' print(ba) # bytearray(b'Hello!') ba = bytearray(b'Hello') ba.extend(b' World') print(ba) # bytearray(b'Hello World') ba = bytearray(b'Hello') # Convert to bytes bytes_obj = bytes(ba) print(bytes_obj) # b'Hello' # Convert to string string = ba.decode('utf-8') print(string) # 'Hello'  ( 6 min )

When I interview new developers or review resumes, I keep hearing the same question: Did I pick the right first programming language? Some candidates list four languages, trying to prove they’ve explored everything. Others feel they picked the wrong one—learning Python instead of Java somehow set them back.
